Question

The tax on the purchase was $ 0.12 .What
is the tax rate at the​ airport? Round to the nearest percent.

Answer 1

23% is the answer i believe

Answer 2

Explanation:

First of all, subtract 0.12 from 2.79. If you do that you assume that the 2.79 includes the tax, so you want to base purchase price.

2.79 - 0.12 = 2.67

The tax is 12 cents on 2.67

% = 0.12/2.67 * 100 = 0.0449 * 100 = 4.49%.

To the nearest % it would be 4%
