Question

FAN AND MEDAL!!!
Debbie sells cookies and hotdogs. The daily cost of making cookies is $460 more than the difference between the square of the number of cookies sold and 20 times the number of cookies sold. The daily cost of making hotdogs is modeled by the following equation:

C(x) = 2x2 - 80x + 1,200

C(x) is the cost in dollars of selling x hotdogs.
