The tax rate is
% (Round to the nearest percent as needed.)

Answer 1

4 percent.

Explanation:

To solve this problem we have to find the percent $0.12 is of $2.79.

0.12 = x * 2.79

0.12 divided by 2.79 = 0.04301075268

We have to round to the nearest percent, so that's 0.04, or 4 percent.

The tax rate at the airport is 4 percent.

Answer 2

The tax rate is 4.3%

Explanation:

First, we have to assume $2.79 is 100%. We know that x% equals 0.12 of the output value. Now we have two simple equations: 100%=2.79 and x%=0.12.

Then, 100%/x%=2.27/0.12 and that gives us 4.3%!

Hope this helps.
