Given:
a.) A cashier worked an 8-hour day and earned $58.00.
To be able to determine how much do the cashier earns per hour, we will be using the following equation:
[tex]\text{ Earnings per hour = }\frac{Daily\text{ earnings}}{Numbe\text{r of hours worked}}[/tex]This equation means that to be able to determine the cashier's earning per hour, we divide his/her earnings by the number of hours he/she worked.
We get,
[tex]\text{ = }\frac{\text{ \$58}}{8\text{ Hours}}[/tex][tex]\text{ = \$7.25 per hour}[/tex]Therefore, the cashier is earning $7.25 per hour.
