Teresa went out to lunch with her sister. The bill was $32.20. She had a coupon for 10% off the bill. Then, she had to pay 7% tax on the discounted
total. What is the total cost that Teresa paid for lunch?

$31

Step-by-step explanation:

First, to find how much the total was after we coupon we have to multiply 32.20 by 0.10. when we do that we get 3.22. Since the coupon was a discount we subtract 3.22 from 32.20 to get 28.98. We then multiply 28.98 by 0,07 to find out how much the 7% tax is. When you do that you get 2.0286. Add that to 28.98 since the tax add to the price. When you do that your answer round up to $31.
