Question

Baseball cards cost $3.79 a pack there is a 25% discount if 10 or more packs are purchased.Sales tax is 7%.If terry bought 15 packs of cards,about how much did he pay

Answer 1

Total amount he paid = $45.62

Explanation:

Number of packs purchased = 15

Cost per pack = $3.79

Total cost = 3.79*15 = $56.85

Since he purchased more than 10 packs, he gets a discount of 25%.

So, net cost after discount = 56.85*(1-0.25) = 42.6325

There is a sales tax of 7% on this amount

So, net cost after discount and sales tax = 42.6325*(1+0.07) = $45.62

Total amount he paid = $45.62
