As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0.25x + 0.5 and the functions that represents the amount they sell the cookie for can be written as s(x) = 2x. What function represents the profit, P(x), for each function?
The profit it's the money that you make minus the money that you sell. So P(x) = s(x) - c(x) P(x) = (2x) - (0.25x + 0.5) P(x) = 2x - 0.25x - 0.5 P(x) = 1.75x - 0.5
