Ella purchased a game that was on sale for 12% off. the sales tax in her county is 6%. let y represent the original price of the game. write an expression that can be used to determine the final cost of the game. y − 0.12y 0.06(0.88y) 1.06(0.88y) y − 0.88y + 0.06y

y:  original price (in dollars)

0.12y:  amount of discount (in dollars)

sale price:  y - 0.12y = 0.88y

sales tax on this sale price:  (0.06)(0.88y)

final cost:  0.88y + (0.06)(0.88y) = 0.88y(1+0.06) =  0.9328y

y − 0.12y
