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

so 18% off means that he paid 82% of the price, right?

since you can say that 82% is 0.82, so for the product BEFORE taxes he paid 0.82y

However, he also had to pay taxes,which is 8% or,it other words, he paid 108% for the game. Since 108% is 1.08,so for the game he paid (0.82*1.08)y=?
