Answer:
Kelly earns more.
Explanation:
Find how much Luna makes first.
24hx8days=192 hours
Then put the 192 hours into groups of 4.
192h/4h=48
Now, we take 48 x 500 to find how much Luna makes.
48x$500=$24000
Now, we have found how much Luna makes. Now, we find how much Kelly makes.
24hx10d=240h
Then put the 240 hours in groups of three.
240h/3h=80
Now, we take 80x$490
80x$490=$32900
