Step 1: Calculate the cost without discounts.

Martha wants to buy two shirts, and each shirt costs $20.

Option A: Buy one shirt and get the second shirt at 50% off
Step 2: Calculate the cost for Option A.

50% off of $20 is:
Total cost for Option A:

Option B: Use a coupon for 30% off the entire purchase
Step 3: Calculate the cost for Option B.

Cost without discounts: $40 (calculated earlier).

Calculate 30% discount:

Total cost after applying the coupon:

Summary of Costs:
Total cost for Option A: $30
Total cost for Option B: $28
Conclusion:
Martha should choose Option B since it has the lower total cost of $28 compared to Option A's $30.

Answer 1

To compare Martha's options for buying shirts, we will calculate the costs after discounts.

Initial Cost:

• Martha wants two shirts, each costing $20.
• Total without discounts: $40.

Option A: Buy one shirt, get the second at 50% off.

• Cost for the first shirt: $20
• Cost for the second shirt at 50% off: $10
• Total for Option A: $30

Option B: Use a 30% off coupon for the total purchase.

• 30% of $40 = $12
• Total for Option B: $40 - $12 = $28

Conclusion: Martha should choose Option B, which costs $28, compared to Option A's $30.
