A pack of cinnamon-scented pencils sells for $7.00. What is the sales tax rate if the total cost of the pencils is $7.28?

Lerok [7]

First divide the new amount (7.28) by the original amount (7) and then times by 100

7.28 / 7 x 100 = 104

This tells us that 7.28 is 104% of 7
Minus this by 100 to get the sales tax rate:
104 - 100 = 4%

You could also subtract 7.28 by 7 first, then divide that by 7 and then multiply by 100:

7.28 - 7 = 0.28
0.28 / 7 x 100 = 4%
