Jon had 45 dollars in his account. He made 7 dollars
per hour at his job. At the end of the week he had 150
dollars in his account. How many hours did he work?
First, 150-45 because we already know he had 45 dollars so we are left with 105$ so next you do 105$ divided by 7$ which gives you 15 hours. The answer is 15 hrs :)
