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?
Dan spent an hour doing 400 tasks * $.25 = $100.
Dan spent an hour doing 5 tasks * $2.00 each = $<<5*2=10.00>>10.00.
Dan made $100 - $10 = $<<100-10=90.00>>90.00 per hour more doing the higher paid work.
