How much did Dan spend in an hour? ** Dan spent an hour doing 400 tasks * $.25 = $100.
How much did Dan spend in an hour? ** Dan spent an hour doing 5 tasks * $2.00 each = $<<5*2=10.00>>10.00.
How much more did Dan make doing the good work compared to the lower-paid work? ** Dan made $100 - $10 = $<<100-10=90.00>>90.00 per hour more doing the higher paid work.
