Answer:
The equation representing the situation can be given as:
![7.84x+9.80y=156.80](https://tex.z-dn.net/?f=7.84x%2B9.80y%3D156.80)
Step-by-step explanation:
Given:
Earnings as a sales person = $9.80 per hour
Earnings from stocking shelves = $7.84
Total earning for the month = $ 156.80
To graph the equation that models this situation.
Solution:
Let
represent the number of hours worked stocking shelves
Total earnings from stocking shelves in dollars will be given as:
![7.84x](https://tex.z-dn.net/?f=7.84x)
Let
represent the number of hours worked as a sales person.
Total earnings as a sales person in dollars will be given as:
![9.80y](https://tex.z-dn.net/?f=9.80y)
Total earnings for the month can be given as:
![7.84x+9.80y](https://tex.z-dn.net/?f=7.84x%2B9.80y)
Total earning for the month = $ 156.80
Thus, the equation representing the situation can be given as:
![7.84x+9.80y=156.80](https://tex.z-dn.net/?f=7.84x%2B9.80y%3D156.80)
The above equation can be graphed with x-axis representing the number of hours worked stocking shelves and y-axis representing the number of hours worked as a sales person.
