A store is offering a 15% discount on all items. Also, employees get a 20% employee discount.

Question

Write a composite function to model taking the 15% discount and then the 20% discount.

f (x) = 0.68x

f(x) = 0.80x

f(x) = 0.85x

f(x) = 0.65x

Answer 1

f(x) = 0.85(0.80x) = 0.68x

Therefore, the composite function to model taking the 15% discount and then the 20% discount is f(x) = 0.68x.
