i don't live in a state with sales tax so i'm really confuesd.
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.
f(x) = x – 7; $148.93
f(x ) = 0.07x; $10.50
f(x ) = 7 + x; $151.07
f(x ) = 1.07x; $160.50
