A local electronics store is offering a $200.00 rebate along with a 20% discount. Let x represent the original price of an item in the store. Find the composite function (D ° R)(x) Group of answer choices 200 – 0.8x 0.8x (0.8x – 80) 0.8x – 200 0.8x - 80

0.8(x - 200)

Step-by-step explanation:

The rebate function is subtracting 200 from the price.

R(x) = x - 200

The discount function is to take 20% off the original price which means to pay for 80% of the original price.

D(x) = 0.8x

(D ° R)(x) =

= D(R(x))

= D(x - 200)

= 0.8(x - 200)
