Given the rationale, provide a reasonable question and answer. Step-by-step reasoning process: 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.
 The question and answer:
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?
The answer is 90
