The amount or money you earn at your job varies directly with the number of hours you work. How many hours will you need to work to earn $145 if you earn $21.75 for 3 hours?
First you have to divide 21.75 and 3 to find out how much each hour costs. which would be 7.25. then you would divide 145 by 7.25 to find out how many hours you would work. so the answer is 20.
Well what you have to do is find out how much money u get per hour which would be 21.75/3 which would give u 7.25 so then you need to do 145/7.25 your answer is 20
