Help me :(

David earned $57.60 in eight hours and John earned $90 in 12 hours who earned more in per hour?

Answer 1

John earned more in per hour by 30 cents

Explanation:

First you need to find how much david makes an hour. Divide 57.60 by 8 this gets you $7.20 an hour. Now figure out how much John earned an hour. Divide 90 by 12 this will get you $7.50. Subtract 7.50 by 7.20 John earns 30 cents

Answer 2

Divide both earnings by how much they both worked.

David: 57.60 / 8 = $7.20 per hour.

John: 90 / 12 = $7.50 per hour.

John earns 0.30 cents more than David hourly.

Hope This Helped! Good Luck!
