Question

Martha is buying two shirts that each cost $20 at a local store. She is considering two options to purchase. The shirts option a use the store sale by one shirt and get the second shirt 50% off the original price or option be use a coupon for 30% off the entire purchase. Martha will also pay 7% tax on her purchase Which option will cost less money.

Answer 1

Option A: Using the store sale, Martha will pay $20 for the first shirt and $10 for the second shirt (50% off). This totals $30 for the two shirts.

Option B: Using the coupon for 30% off the entire purchase, Martha will pay $20 + $20 = $40 for the two shirts. After applying the 30% discount, she will pay $40 - ($40 * 0.30) = $28 for the two shirts.

In both options, Martha will pay 7% tax on her purchase.

Option A (with tax): $30 + ($30 * 0.07) = $32.10
Option B (with tax): $28 + ($28 * 0.07) = $29.96

Therefore, option B will cost less money as Martha will pay $29.96 instead of $32.10 with option A.
