Question

If the revenue of a cookie company is f(x) = 2.5x + 16, where x is the number of cookies sold, and the expenses of the company are g(x) = x + 20, where x is also the number of cookies sold, what is the profit of the company if they sell 126 cookies?

Answer 1

profit = revenue - expenses.

so p(x) = f(x) - g(x)
find p(126)
p(126) = f(126) - g(126)

Answer 2

so that means the profit 185.00
