Question

4) If Trina multiplied her purchase price by 1,07 to get her total bill. what percent sales tax was she paying?​

Answer 1

7%

Explanation:

When multiplying with decimals as percentage rates, we start with the original 100% in something. That is also represented as 1.00. Since Trina multiplied with 1.07, that .07 is the amount added, which is 7% when converting the decimal to a percent.
