Answer:
Pio is paid with $ 401.25 for 51 hours in a week.
Explanation:
Based on the information of the statement we can calculate his payment for 51 hours in a week but using this arithmetical formula:
![c = 7.50\,(\$)/(h)* 46\,h + 1.5* 7.50\,(\$)/(h)* (51\,h-46\,h)](https://img.qammunity.org/2022/formulas/mathematics/high-school/24k7sliwkf2robatzy1y03fflxtmhjt0fd.png)
![c = \$\,401.25](https://img.qammunity.org/2022/formulas/mathematics/high-school/sgo7tsrnjtzq99tqfy5snn095gzwp08d44.png)
Please notice that first component of the sum represent the ordinary time in a week (46 hours) and the second one, extra work time.
