The marginal gain from Bob’s fourth hour of work, from 11:00 AM to noon, is problems. Later, the teaching assistant in Bob’s economics course gives him some advice. “Based on past experience,” the teaching assistant says, “working on 22.5 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour.” For simplicity, assume students always cover the same number of pages during each hour they spend reading. Given this information, in order to use his 4 hours of study time to get the best exam score possible, how many hours should he have spent working on problems, and how many should he have spent reading? 0 hours working on problems, 4 hours reading 2 hours working on problems, 2 hours reading 3 hours working on problems, 1 hour reading 4 hours working on problems, 0 hours reading
