The sales tax in one state is 7%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $150. a. f(x) = x – 7; $148.93 c. f(x) = 7 + x; $151.07 b. f(x) = 0.07x; $10.50 d. f(x) =1.07x; $160.50
I'll give you a hint, the tax of 7% you have to times the item's selling price x and also the number in front must be greater than 1.
