The final cost of the cards can be determined by subtracting the discount and adding the sales tax to the original price.
The discount is 22% of the original price, which can be expressed as 0.22y.
The sales tax is 6% of the discounted price, which can be expressed as 0.06(0.78y) since the discounted price is 78% of the original price after applying the discount.
Therefore, the expression to determine the final cost of the cards is: y - 0.22y + 0.06(0.78y).
Jackson purchased a pack of game cards that was on sale for 22% off. The sales tax in his county is 6%. Let y represent the original price of the cards. Write an expression that can be used to determine the final cost of the cards.

the sales tax applies to the discounted price
1 - 0.22 = 0.78
1+ 0.06 = 1.06
so I get cost = y * 0.78 * 1.06
1 - 0.22 = 0.78
1+ 0.06 = 1.06
so I get cost = y * 0.78 * 1.06
Apologies for the incorrect information in my previous response. You are correct.
The final cost of the cards can be determined by multiplying the original price by the discount factor (1 - 0.22) and then multiplying that by the tax factor (1 + 0.06).
Therefore, the expression to determine the final cost of the cards is: y * 0.78 * 1.06.
The final cost of the cards can be determined by multiplying the original price by the discount factor (1 - 0.22) and then multiplying that by the tax factor (1 + 0.06).
Therefore, the expression to determine the final cost of the cards is: y * 0.78 * 1.06.
