Question

becky bought a magazine for $3.90 , and the sales tax was 8.25%.how much sales tax did becky pay on the magazine?

Answer 1

Multiply the original amount by the decimal equivalent of the percentage.

Explanation:

A "percent" is literally "per 100", so to make a calculation you just divide the value by 100 to get the decimal value. That is then applied to the original amount to obtain the amount desired.

8.25100=0.0825

0.0825×540=44.55
