Elijah gets paid $15.50 per hour in addition to a weekly salary of $50. This week he wants to earn more than $400. How many hours will he need to work?

H=number of hours

m=total salary

m=15.50h+50

put 400 in for m

400=15.50h+50

now solve for h

400=15.50h+50

-50. - 50

350=15.50h

Divide 350 by 15.50to get your final answer

you get a long decimal so I rounded it.

22.6 hours
