Answer :
Tim would be able to mow all three lawns at a price of $23, because all three of his neighbors would be willing to pay at least that much. Tim would receive a total of $23 x 3, or $69 for mowing the three lawns.
Tim's "supply curve" would be: he would be willing to mow three lawns for a total of $13 + $19 + $23, or $55.
He receives $69 for something that he would be willing to do for $55, so his producer surplus would be $14.
