Question

The sales tax for an item was $8.80 and it cost $440 before tax.

Find the sales tax rate. Write your answer as a percentage.

Answer 1

Explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%
