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.

final price = .8856y

Step-by-step explanation:

y =original price of the game

discount = y* 18 percent

discount = .18y

new price = original price -discount

new price = y -.18y

factor out the y

new price = y(1-.18)

new price = y(.82)

now we need to add tax

tax= new price * .08

tax = y (.82) (.08)

tax = y (.0656)

final price = new price + tax

final price = y (.82) + y (.0656)

final price = .8856y

1.08 (.82y)

Step-by-step explanation:

Discount the game before adding taxes

Since y=100% of the price of the game

100-18%=82%

Meaning you are only paying for 82% of the full game price making your equation .82y to find out the price of the discounted game

Now you have to add the taxes at 8%.

1.08 (.82y) = the final price of the discounted game plus taxes.

y=x+9
