Jonah is purchasing a car that is on sale for 15% off. he knows the function that represents the sale price of his car is c(p) = 0.85p, where p is the original price of the car. he also knows he has to pay 9% sale's tax on the car. the price of the car with tax is f(c) = 1.09c, where c is the sale price of the car. determine the composite function that can be used to calculate the final price of jonah's car by solving for f[c(p)]. answers a. f [c(p)] = 0.9265cp b. f[c(p)] = 0.9265p c. f [c(p)} = 1.94cp d. f [c(p)] = 1.94p
