Answer:
Bill will need to work 50 hours every month.
Step-by-step explanation:
First, we subtract the stipend from the total income he wants to have since he will already recieve it.
[tex]1200 - 800 = 400[/tex]
From this 400 dollars, we can divide it by 8, or his hourly rate to find the rest of the time he needs to work.
[tex]\frac{400}{8}=50[/tex]
Bill needs to work 50 hours to make his total income of 1200.
Hope it helped!
