I have this problem "A car dealership advertises a 15% discount on all its new cars. In addition, the manufacturer offers a $1,000 rebate on the purchase of a new car. Let x represent the sticker price of the car."
a)Suppose only the 15% discount applies. Find a function f that models the purchase price of the car as a function of the sticker price x.
f(x)=(100%-15%)=.85x
b) Suppose the $1000 rebate applies. Find a function g that models the purchase price of the car as a function of the sticker price x.
g(x)=x-1000
c) Find a formula for H=f(g(x))
I'm stuck on finding the formula for f(g(x))
