   Faville, J.

The appellants secured a certain contract for the construction of a. drainage ditch. They were the owners of a dredge boat which they wished to use in the work of constructing said ditch.. It appears that the dredge boat was not in good order, and that the appellee had had experience in the management and operation of such a boat. The jury were warranted in finding, under the evidence, that the appellants and the .appellee entered into an oral agreement whereby the appellee was to operate said dredge boat in the construction of said ditch, and the appellants .were to .furnish.said boat, and that the appellee was to receive for Ms services one half of the net profits, after all expenses for material, labor, and other items in constructing said ditch had been paid. This suit is for the balance claimed to be due to the appellee.

I. Appellants contend that there was error in the ruling of the court in admitting the testimony of the appellee with regard to the amount of profits. It is urged that the evidence was mere opinion evidence, that the proper foundation had not been laid, and that it was an invasion of the province of the jury. The appellee, as a witness in his own behalf, produced a written memorandum or statement of account, wMch he testified was furnished to' him by the appellants. Said statement of account, while somewhat crude and inartistic in form, purported to show the total amount that had been received by the appellants on said contract and the total amount of expenditures that had been incurred. The appellee ivas asked whether he knew, from any-tMng that the appellants had told him, or from his own personal knowledge, what the profits were on the work that was done, and he answered in the affirmative. He had before him the statement furnished him by the appellants. In ruling upon the objections to his testimony, the court held that, “If he knows what it is, he may say. ’ ’ The witness testified to the difference between the amount of the receipts and the expenditures, wMch would be the profits. TMs was shown upon the statement which was in evidence. TMs was not the conclusion of the witness, but, it appears, was a mere mathematical computation. Strictly speaking, it was within the province of the jury to make the subtraction of the amounts shown on the statement; but it certainly cannot be held to be prejudicial error that the witness, after having given the figures as to the amounts of the receipts and expenditures, testified as to the balance. Reversible error could not be predicated upon the admission of this testimony, under the record.

II. It is contended by the appellants that the record shows a settlement of the matters involved between the parties, which constituted an accord and satisfaction, and is, therefore, a com-píete bar to the appellee’s right to recover, Upon this question it appears that, during the course of the work, the appellants had paid the appellee the sum of $200, and that thereafter' the appellee requested of tbe appellants that they furnish him a statement, and make further payment. It appears that the appellants furnished such a statement to the appellee, and with it a check payable to the appellee. In regard to said matter the appellee testified:

‘ ‘ He had the statement all written out for me, and a check and everything, when I came up here to Onawa. I had demanded that he make a settlement. He didn’t say anything,— only handed over that statement. I argued with him a little while, that it wasn’t right. He said it was. So I did not stop very long; I just took the check, and then I went up town and saw an attorney. * * * With reference to this statement, Exhibit I, as I said before, he just called me in. He had the check lying on the table, and the statement lying on the table. He says, ‘ Here it is. ’ So I looked at the check and I looked at the statement. I saw it was not what we agreed to. We argued back and forth on this. We had a few other words I don’t remember just now. * * * When Mr. Osman handed me this statement, Exhibit I, he didn’t say it was a correct statement. He just laid it on the table, and the check was there. He says: ‘Here’s the statement and here’s the check. ’ I looked at it, and I says: ‘ He is charging me with all the expense. ’ I had made a demand for settlement. I asked him for a statement of all the money received and all the expense. He says, ‘Here it is.’ Took it and pushed it over the table, and says: ‘ Here it is. ’ ”

The contention of the appellants was that the check, which was for $224.79, was given to the appellee at the time the statement was rendered, and was in full settlement of the amount due. In rebuttal, on cross-examination, the appellee testified:

“ Q. You took the check that he gave you as a part payment? A. Yes, I told him it was not a settlement. Q. You cashed it, didn’t you? A. Yes.”
In Perin v. Cathcart, 115 Iowa 553, we said:

“But, as an accord and satisfaction is an executed agreement whereby one of the parties undertakes to give, and the other to accept, in satisfaction of a claim arising either from contract or tort, something other or different from what he is or considers himself entitled to, no invariable rule can be laid down, with any degree of certainty, as to what constitutes such an agreement. Each case must be determined largely on its peculiar facts. To constitute a valid accord and satisfaction, not only must it-be shown that the debtor gave the amount in satisfaction, but that it was accepted by the creditor as such. ’ ’

See, also, Rustler Realty Co. v. Swecker, 134 Iowa 679; Beaver v. Porter, 129 Iowa 41; Sparks v. Spaulding Mfg. Co., 158 Iowa 491; Schultz v. Farmers Elevator Co., 174 Iowa 667.

It is undoubtedly true that, where a debtor tenders a sum on the condition that it be accepted in discharge of the whole debt, the creditor- is bound to either reject the amount offered or accept it on such condition; and if, under such- circumstances, he accepts the sum tendered, there is an accord and satisfaction. Ferguson v. Grand Lodge, 174 Iowa 61. Under the record in this case, we are .of the opinion -that the trial court did not err in submitting to the jury the question as to whether or not there was an accord and satisfaction. The evidence is not so clear and conclusive that the appellants tendered the check at the time they furnished the statement to the appellee, in full payment of any sum that might be due the appellee, or that the appellee, with knowledge that the check was so tendered in full payment, accepted it, as to make it a question for the court.' We think that the question as'to whether or not there was an accord and satisfaction was a proper one for the consideration of the jury, and that the court did not err in submitting it to the jury and in-overruling the appellants’ motion for judgment- notwithstanding the verdict, upon this ground.

III. Appellants pleaded as an affirmative defense that the action was prematurely brought, and now contend that the court should-have so found; and entered judgment accordingly. The appellants-’ contention in this regard is that the contract between the appellants and the appel-lee -^s for the complete- construction of a certain ditch, called the Fensler Ditch, and laterals thereto; that, at the time the appellee instituted said action, the laterals had not been completed; that the- said contract had not been fully performed; that the amount of profits could not be ascertained until the work was completed; and that said action was, therefore, premature. The appellee’s contention in regard to said matter was that, after said, work upon the main ditch had been performed by -the appellee, appellants, without the knowledge or consent of the appellee, made a new contract, by which a material change was made in relation to the dredging to be done upon the laterals, and informed appellee that he need not use the dredge machine upon said laterals, but that the same would be done by the work of teams. Upon this question there was a conflict in the testimony. The court submitted the question to the jury, and instructed the jury to the effect that, if they found from the evidence that, under the terms of the oral agreement in question, the appellee agreed to do the work of the entire job, and that same had not been completed at the time of the commencement of the action, and if it had not been shown what, if any, profits there would be on the entire job, in that event the appellee could not recover. The court also instructed the jury on the alleged claim of a change in the contract. We think that the question as to whether the action was prematurely brought, and whether there had been a change in the contract, was one, under the peculiar circumstances of this case, that was clearly for the determination of the jury. The finding of the jury has support in the evidence upon this question, and we would not be warranted in interfering with this finding, under the record.

We find no error requiring interference with the judgment of the district court in any of the matters urged by the appellants, and the judgment appealed from must, therefore, be, and it is, — Affirmed.
