Tess earned $52 for 44 hours of shoveling snow and $71.50 for 5.5 hours of shoveling snow. How long would she have to shovel snow to earn $39?

Respuesta :

Here is how I would solve this problem:

52/4 = 13

13.00 for 1 hours worth of work

6.50 for 30 minutes of work

13*3=39.00

Therefore, she would have to work 3 hours to earn 39.00
