Game Stop has a deal on NBA 2K20. The deal lets you get the game for 15% off! TODAY ONLY! Sarah has a coupon that allows her to get an additional $15 off! 18. Write a function that you can use to determine The cost of NBA 2K20 if Sarah uses the in- store discount FIRST.

The function that represents the cost of the game as a function of it's original price is f(x) = 0.15*x - 15.

Step-by-step explanation:

In order to write a function we will attribute a variable to the original price in dollars of the game, this will be called "x" and the price paid by Sarah will be "y". So if the in-store discount is used first we have 15%*x or 0.15*x, and we subtract $15 from that value because of her coupon. We have:

y = f(x) = 0.15*x - 15

The function that represents the cost of the game as a function of it's original price is f(x) = 0.15*x - 15.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
