Question

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.

Answer 1

Answer:

Final cost=1.08(.82y)

100 is the whole of the sale and if you subtract 18 from the whole 100 you get 82. and for the tax you add 8 to 100 but you need them to be decimals.

Answer 2

(y*0.08)-0.18=x x being the final cost
