Question

The grocery store has a special deal on potato chips where if you buy 1 bag you get the second bag for 50% off. If the sales tax is 5%, how much is your total purchase for 3 bags of chips if each bag costs $2.50?

Answer 1

2(2.50) + 0.50(2.50) = 5 + 1.25 = 6.25
6.25 + 0.05(6.25) = 6.25 + 0.31 = 6.56 <== total price
