When most economists wake up in the morning their first decision is whether or not to hit the snooze bar on the alarm clock What statement best represents their thought process as a rational decision maker O I had a really late night grading exams and I deserve 10 more minutes of sleep The total amount of work I have to do today is rather small so the total benefit to going to work for a full 8 hours is also small The total amount of work I have to do today is rather small so the marginal cost of going to work 10 minutes late is small O The total amount of work I have to do today is rather small so the marginal benefit of sleeping 10 more minutes is rather large The marginal benefit of sleeping 10 more minutes is greater than the marginal benefit of 10 more minutes of work
