Question

Ms. Pierce ordered pizza for her class. The total was $52.30. She had a 10%off coupon that she used. After the coupon, she had to pay 7% tax as well. What is the total cost that Ms. Pierce paid for the pizza after the coupon, including tax?

Answer 1

To find the total cost that Ms. Pierce paid for the pizza after the coupon, including tax, first calculate the discount amount, subtract it from the total cost, then calculate the tax amount and add it to the post-discount cost.

Step-by-step explanation:

To find the total cost that Ms. Pierce paid for the pizza after the coupon, including tax, we can use the following steps:

1. Calculate the amount of discount by multiplying the total cost by the discount percentage: 10% of $52.30 = $5.23
2. Subtract the discount amount from the total cost: $52.30 - $5.23 = $47.07
3. Calculate the amount of tax by multiplying the post-discount cost by the tax percentage: 7% of $47.07 = $3.29
4. Add the tax amount to the post-discount cost: $47.07 + $3.29 = $50.36

Therefore, the total cost that Ms. Pierce paid for the pizza after the coupon, including tax, is $50.36.
