In the unit on supply, we established that sellers derive their utility from profits, or the  amount of money that they actually make from a sale. Roughly speaking, this means  that when the price of a good goes up, the seller will be happier, but there is more to  profit than the sale price of a good. For instance, we would think that Kenny, who sells  shirts, would be happier if the selling price went from \$20 a shirt to \$25 a shirt. If nothing  else changes, then that's true: he will be happier at the higher price. If with the higher  sale price his costs change, however, from an initial cost of \$10 a shirt to a cost of \$17 a  shirt, then he would have been happier at the lower price, since his profits now are  actually decreased.  Profit = Total Revenue (TR) - Total Cost (TC)  Kenny's initial profit per shirt is:  Profit = 20 - 10 = \$10 a shirt
