Question

Ray is purchasing a laptop that is on sale for 25% off. He knows the function that represents the sale price of his laptop is c(p) = 0.75p, where p is the original price of the laptop. He also knows he has to pay 8% sales tax on the laptop. The price of the laptop with tax is f(c) = 1.08c, where c is the sale price of the laptop.

Determine the composite function that can be used to calculate the final price of Ray's laptop.

c[f(c)] = 0.81c
c[f(c)] = 1.83c
f[c(p)] = 0.81p
f[c(p)] = 1.83p
