B) 1.08(0.87y)
C) 0.08(0.87y)
D) y − 0.87y + 0.08y
Answer:
1.08(0.87y)
Explanation:
Let initial cost = y
Cost on sale = 13% off
Discounted price = y - 0.13y = 0.87y
Sales tax on purchase = 8%
Sales tax is ade d to the purchase price of item, hence ;
Sales tax = 1 + 0.08 = 1.08
The final cost of card is:
Sales tax * discounted price
1.08 * 0.87y
1.08(0.87y)
