Question

All computers are on sale for 10% off the original price.

If x is the original price of the computer, then the function that represents the price after only a 10% discount is:


P(x) = x - 0.1x


P(x) = 0.9x


The function that gives the price, C, if only a $150 coupon is used is:


C(x) = x - 150


Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.


C(P(x)) = 0.9x – 150


P(C(x)) = 0.9x – 150


C(P(x)) = 1.9x – 150


P(C(x)) = 1.9x – 150
