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- buy one shirt and get a second shirt at 50% off the original price. Option B: 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

Let's calculate the total cost for each option:

Option A:
- Buy one shirt at $20
- Get the second shirt at 50% off, so it will cost $20 * 0.5 = $10
- Total cost before tax: $20 + $10 = $30
- Total cost after tax: $30 * 1.07 = $32.10

Option B:
- Total cost before coupon: $20 + $20 = $40
- Total cost after coupon: $40 * 0.7 = $28
- Total cost after tax: $28 * 1.07 = $29.96

Therefore, Option B will cost less money for Martha.
