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% sale's 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 by solving for f[c(p)].
f[c(p)] = 1.83p
f[c(p)] = 1.83cp
f[c(p)] = 0.81p
f[c(p)] = 0.81cp
