## Elementary Algebra

The total amount paid was 98.24 dollars. This sum had two parts, the monthly-plan charge and the extra minutes charge. So, the monthly-plan charge + the extra minutes charge = 98.24 The monthly-plan charge equals 29.99 dollars. So, 29.99 + the extra minutes charge = 98.24 The extra minutes charge = 98.24 - 29.99 The extra minutes charge = 68.25 Jean-Paul was charged 68.25 for 195 minutes. For each minute, he was charged 68.25 $\div$ 195. $\frac{68.25}{195}$ = 0.35 Jean-Paul was charged 0.35 dollars for each extra minute.
