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?
Option B
To determine which option will cost less money, we need to calculate the total cost of each option.
Option A:
Martha will pay full price for the first shirt, which is $20.
For the second shirt, she will get 50% off the original price, which is $20 * 50% = $10.
So the total cost for Option A is $20 + $10 = $30.
Option B:
Martha will get 30% off the entire purchase.
So she will pay 70% of the total cost, which is $20 * 2 = $40.
Therefore, the total cost for Option B is $40 * 70% = $28.
Martha will also pay 7% tax on her purchase, regardless of the option chosen.
7% of $30 is $30 * 7% = $2.10.
7% of $28 is $28 * 7% = $1.96.
Adding the tax to the total cost, the final cost for Option A is $30 + $2.10 = $32.10.
The final cost for Option B is $28 + $1.96 = $29.96.
Therefore, Option B will cost less money.
