Answer:
Bill will need to work 50 hours every month.
Explanation:
First, we subtract the stipend from the total income he wants to have since he will already recieve it.
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.
Bill needs to work 50 hours to make his total income of 1200.
Hope it helped!
