Question

The revenue from selling x shirts is r(x)=12x.

Answer 1

Answer:

p(x) = 7x - 20

Step-by-step explanation:

A company makes a profit selling goods when the revenue taken in from the sales is greater than the cost of those goods:  p(x) = r(x) - c(x) > 0.

In this case the revenue function is r(x) = 12x; the cost function is c(x) = 5x + 20, and the profit function is p(x) = 12x - (5x + 20), or:

p(x) = 12x - 5x - 20, or

p(x) = 7x - 20
