Question

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?

Answer 1

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

Answer 2

profit=selling rice-cost price
P(x)=2x-(0.25x+0.5)
P(x)=1.75x-0.5
