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