Question

In the mail, you receive a coupon for $5 off of a pair of jeans. When you arrive at the store, you find that all jeans are 25% off. Define two functions that represent the two types of discounts separately. Let f(x) be the dollars off and g(x) be the percent off. Then choose which composition of functions gives you the best price for a $40 pair of jeans. Then state what that best price is exactly.

1.) Composition of functions: Type in f(g(x)) or g(f(x)):

2.) Price of a pair of Jeans: $

3.) What is the difference in the the two prices? $

Answer 1

assuming f and g calculate the discounted price, then
f(x) = x-5
g(x) = 0.75x
now see what you can do with that
