Question

Elena babysits her neighbor’s children. Her earnings are given by the equation $y=8.40x, where $x represents the number of hours she worked and y represents the amount of money she earned.



Jada earns $7 per hour mowing her neighbors’ lawns.



b. What is Elena's rate of change and what does it mean?

Answer 1

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
