Question 5 (essay worth 5 points) emerson purchased a game that was on sale for 18% off. the sales tax in his county is 8%. let y represent the original price of the game. write an expression that can be used to determine the final cost of the game.

0.9y

Step-by-step explanation:

The original price of the game is y.

cost off ⇒ 18% of y = 18/100 × y = 0.18y

Added cost ⇒ 8% of y = 8/100 × y = 0.08y

Final cost of the game = y - 0.18y + 0.08y

                                     = 1.08y - 0.18y

                                     = 0.9y
