Answer the following question, with explanation first.
Dan spent an hour doing 400 work tasks at $0.25 each. Then Dan spent an hour doing 5 work tasks at $2.00 each. How much more did Dan make doing the good work compared to the lower-paid work?

90
Dan spent an hour doing 400 tasks * $.

25 = $100.

Dan spent an hour doing 5 tasks * $2.

00 each = $10.

00.

Dan made $100 - $10 = $90.

00 per hour more doing the higher paid work.
