Tim mows neighborhood lawns for extra money. Suppose that he would be willing to mow one lawn for ​$13​, a second lawn for ​$17​, and a third lawn for ​$24. Also suppose that three neighbors are interested in having their lawns mowed. Mrs. Jones would be willing to pay ​$32 to have her lawn​ mowed, Mr. Wilson would be willing to pay ​$28​, and Ms. Smith would be willing to pay ​$24.
If Tim offers to mow lawns for ​$24 ​each, what will be his producer​ surplus?  ​
