Question

France is a hand-working freshman in college. One Saturday, she decides to work nonstop until she has answered 100 practice problems for her economies course. She starts work at 8:00 AM and uses a table to keep track of her progress throughout the day. She notice that as she gets tired, it takes her longer to solve each problem. Use her table Below to answer the following questions. The marginal, or additional, gain from Frances's first hour of work, from 8:00 AM to 9:00 AM, is problems. The marginal, or additional, gain from Frances's third hour of work, from 10:00 AM to 11:00 AM, is problems. Later, the teaching assistant in Frances's economics course gives her some advice. "Based on past experience," the teaching assistant says, "working on 15 problems raises a student's exam score by about the same amount as reading, the text book for one hour." For simplicity, assume students always cover the same number of pages during each hour they spend reading. Given this information, if France's goal had been to use her four hour of study time to get the best exam score possible, how many hours should she have spent working on problems and how many should she have spent reading? One hour working on problems, three hours reading Two hours working on problems, two hours reading Three hours working on problems, one hour reading Zero hours working on problems, four hours reading

Explanation / Answer

First answer is 40-0=40 second answer is 90-70=20 Last answer is three hours working on problems then one reading. We know this because the last answer of problems has a marginal gain of only 10 while reading adds 15. Hope this helps
