regular price of the item. The function g (x) = 1.07x is used to determine the

total amount customers pay for a purchase after all discounts are applied. Which

function can be used to determine T (x), the total amount a member pays for an

item with a regular price of x dollars?

A. T (X) = 0.17%

B. T (X) = 0.963x

C. T (x) = 1.19%

D. T (x) = 1.97%
