Question

A $78.00 pair of shoes cost $84.63 after tax is added. What percentage of the cost is tax?

Answer 1

The percent of the cost tax is:

8.5%

Explanation:

Cost of shoe before tax= $ 78

Cost of shoe after tax= $ 84.63

This means that the cost of tax is:

Cost of shoe after tax-cost of shoe before tax

= $ 84.63-$ 78

= $ 6.63

Now, the percent of tax is calculated as:

`Percent\ tax=(Cost\ of\ tax)/(Cost\ of\ shoe\ before\ tax)* 100\\\\\\Percent\ tax=(6.63)/(78)* 100\\\\\\Percent\ tax=8.5\%`

Hence, the percent tax is:

8.5%
