Also suppose that three neighbors are interested in having their lawns mowed. Mrs. Jones would be willing to pay $31 to have her lawn mowed, Mr. Wilson would be willing to pay $30, and Ms. Smith would be willing to pay $24. If Tim offers to mow lawns for $24 each, what will be his producer surplus? $ nothing. (Enter a numeric response using an integer.)
