Question

You are making several purchases from the I.B. Electric electronics store. You can buy from this retailer online or in a physical store. You have a coupon for 15% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 6% only applies to the physical store. Shipping for the online store is a flat rate of $8.99. Using this information and the information below, which way would you save the most money?

Answer 1

Physical store: 15% discount ;6% sales tax.
Online store: $5 off ; shipping fee $8.99

Let us assume that the total item bought costs $100

Physical store:
100 x 15% = 15 discount
100 - 15 = 85 discounted cost of item
85 * 6% = 5.1 sales tax
85 + 5.1 = 90.10 total cost

Online store:
100 - 5 = 95 discounted cost of item
95 + 8.99 = 103.99 total cost

It's cheaper to go and visit the physical store.
