Answer 2

Hello!

`\large\boxed{9 \%}`

To find the percent tax, use the equation:

`\text{ \% tax} = \frac{\text{ price after - initial price}}{\text{initial price}}`

Substitute in the given values:

`\text{ \% tax} = \frac{\text{ 21.80 - 20}}{\text{20}} \\\\\text{ \% tax} = (1.80)/(20) = 0.09`

Multiply by 100 to find the percent tax:

`0.09 * 100 = 9\%`
