Answer:
Total amount he paid = $45.62
Step-by-step 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
