Question

Luna makes $500 per 4 hours and Kelly makes $490 per 3 hours

Luna works 8 days and Kelly works 10 days

Who makes more money?

Answer 1

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
