Julia made a purchase at a furniture store, but it was too big and did not fit into her car. So, she arranged to have the store deliver the purchase for her. She paid for her purchase, plus the sales taxes, plus the fee. The taxes are 5% and the fee is $25.
Write a function t(x) for the total, after taxes, on the purchase amount x.
Write another function f(x) for the total, including the delivery fee, on the purchase amount x.
How much money did Julia spend, if she made a $440 purchase?
A. t(x) = 0.05x ; f(x) = x +25; $47
B. t(x) = 1.05x ; f(x) = x +25; $487.00
C. t(x) = 1.05x ; f(x) = x +25; $488.25
D. t(x) = 0.05x ; f(x) = x +25; $487.00
