Deanna runs a bakery that sells gourmet doughnuts. At $5 per doughnut she sells 100 doughnuts in a day. Her daily costs to make the doughnuts are $175. Deanna estimates that for each $0.50 decrease in cost she will sell
35 more doughnuts each day. The daily profits for the doughnuts can be modeled with the equation:
P(x)=(100+ 35x)(5 -0.5x) -175, where x represents the number of $0.50 decreases in price. Use
technology to graph the profit equation and determine the price per doughnut that Deanna should charge to
maximize her profits.
