Question

When comparing two jobs, Chris noticed that the hours every week were the same at each, but the job at the hospital paid $3.00 per hour more than the job at the mall. She can earn $440 per week at the hospital and $320 per week at the mall. What is the hourly wage at the mall?

Answer 1

You would start off with x=the total number of hours she works
320+3x=440
320-320+3x=440-320
3x=120
3x/3=120/3
x=40
He worked 40 hours at each job
y=hourly wage at the mall
40y=320
40y/40=320/40
y=8
Solution: The hourly wage at the mall would be $8
