Question

Eduardo earns 15 dollars an hour roofing. If he needs 600 dollars per month to pay his monthly bills, how many hours does he need to work if he currently has 100 dollars?

Answer 1

Eduardo's Money = ($15 per hour)*(Number of hours Eduardo works) + ($100 he already has)

 

Since Eduardo needs $600:

 

$600 = ($15)*(Number of hours Eduardo works) + $100

$500 = ($15)*(Number of hours Eduardo works)

$500/$15 = Number of hours Eduardo works = ?
