Question

Choose the composition function that gives the

final sale price after a 10% discount is followed by
a $150 coupon.
O C(P(x)) = 0.9x – 150
O PC(x)) = 0.9x – 150
O C(P(x)) = 1.9x.– 150
O P(C(x)) = 1.9x – 150

Answer 1

A. ) C(P(x)) = 0.9x – 150

Step-by-step explanation:

Answer 2

C(P(x)) = 0.9x – 150

Explanation:

We have to assume that the discount function is ...

P(x) = 0.9x

and the coupon function is ...

C(x) = x - 150

Then applying the coupon to the discounted price is described by ...

C(P(x)) = C(0.9x)

C(P(x)) = 0.9x -150
