Answer:
Elena:
y=8.40*12
y= $100.8
Jade:
y= 7*12
y= $84
Elena receives a higher value per hour, she earns $16.8 more than Jada.
I am unsure of the hours so I put times 12 but if you can give me the hours I would be able to solve it for you more briefly. If you can could please give me the whole question since it is incomplete
