"based on past experience," the teaching assistant says, "working on 70 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 reading1 hour working on problems, 3 hours reading2 hours working on problems, 2 hours reading3 hours working on problems, 1 hour reading
