Answer:

1. $132.24

2. $55.89

3. $1336.66

4. $258.19

5. $57.86

Step-by-step explanation:

Simply use this equation.

$\frac{InitialValue}{100} = \frac{x}{TaxPercentage}$

Substitute in our values, using No.1 as our example.

$\frac{123.01}{100} = \frac{x}{7.5}$

Cross multiply

922.575 = x100

Solve for x by dividing by 100.

x = 9.22575

Now add x to the initial value.

9.22575 + 123.01 = 132.23575

Round to the nearest hundredth for the answer.

$132.24
