Suppose that Maris is a diligent fourth-year college student. One Wednesday, she decides to start the day by working through zoo sample multiple choice problems to study for her informatics dass, She starts work at 7:00 AM and uses a table to ketep track of her propress throughout the day. She notices that as she the hours pass, it takes her more time to solve the problems, Use the tabie to answer the following questions: The margifial, ot additional, gain from Maris's first hour spent working, from 7:00 AM to 8:00 AM, is problems. The marginal gain from Maris's thied hour spent working. from \( 9: 00 \) AM to 10100 AM, is The fotlowing week, Maris's informatics faculty advisor gives her some advice. In all their years of teaching thay claim to obsitve that working on 30 multiphs choice guestions boosts a student's test score by about the rame amount as solinding an hour reviewing liecture notes, For simolicity assume stutents are able to revicw lecture notes af a constant pace during each hour spent studying.
The marginal, or additional, gain from Maris's first hour spent working, from 7:00 AM to 8:00 AM, is problems. The marginal gain from Maris's third hour spent working, from 9:00 AM to 10:00 AM, is problems. The following week, Maris's informatics faculty advisor gives her some advice. In all their years of teaching they claim to observe that working on 30 multiple dhoice questions boosts a student's test score by about the same amount as spending an hour reviewing lecture notes, For simplicity, assume students are able to review lecture notes at a constant pace during each hour spent studying. Glven this information, in order to use her 4 hours of time spent studving to get the highest possible test score, how many hours should she have. spent solving multiple choice problems, and how many hours should she have spent reviewing lecture notes? 0 hours working on problems, 4 hours reading Theur working on problems, 3 hours reading 2 hours working on problems, 2 hours reading 3 hours working on problecns, 1 hour reading
