Jennifer earns $5.50 per hour

Edward earns ($5.50*1.8) $9.90 per hour

Edward earns more per hour

To find out how many hours they'd have to work to make 50$, we would just divide $50 by their hourly wage.

Jennifer=50/5.50=9.09 hours    since you cant have 0.09 hours round up
Jennifer=10 hours to make at least $50 dollars

Edward=50/9.90=5.05 hours    since you cant have 0.05 hours round up
Edward=6 hours to make at least $50 dollars


**Edit. Since Edward earns 1.8 times what Jennifer earns, that means he earns 180% of what she earns or 80% more. So we can tell that he earns more just by the 1.8.

1.8=180%
