The marginal gain from Sam's third hour of work, from 10:00 AM to 11:00 AM, is 40 problems. Later, the teaching assistant for Sam's chemistry course gives him some advice. "Based on past experience," the teaching assistant says, "working on 30 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 spend working on problems and how many should he spend reading? O 0 hours working on problems, 4 hours reading O 1 hour working on problems, 3 hours reading O 2 hours working on problems, 2 hours reading O 3 hours working on problems, 1 hour reading 4 hours working on problems, 0 hours reading

![Sam is a hard-working college junior. One Thursday, he decides to work nonstop until he has answered 220 practice problems for his chemistry
course. He starts work at 8:00 AM and uses a table to keep track of his progress throughout the day. He notices that as he gets tired, it takes him
longer to solve each problem.
