Given:
Maria makes $6.00 an hour plus 5% commission for telephone sales.
Working time = 8 hours
Sales = $600.00.
To find:
The amount that Maria make yesterday.
Solution:
We know that,
1 hour = $6.00
8 hour = 8 × $6.00 = $48.00
Commission = 5% of telephone sales
Sales = $600.00.
![Commission=5* 6](https://img.qammunity.org/2021/formulas/mathematics/high-school/8mqmpztg5holq6njgt93euec91ga6ndf3u.png)
![Commission=30](https://img.qammunity.org/2021/formulas/mathematics/high-school/t6cwmmus86sstyr4hzprgti79hzi7z5t4h.png)
Total amount that Maria make yesterday is the sum of total hourly changes plus commission.
![\$48.00+\$30.00=\$78.00](https://img.qammunity.org/2021/formulas/mathematics/high-school/jqsulmwta73pefr99ejyvwsqy5sl71ugdz.png)
Therefore, the required amount is $78.00.
