Three college students are considering operating a tutoring business in economics. This business would require that they give up their current jobs at the student recreation center, which pays $6,000 per year. A fully equipped facility can be leased at a cost of $8,000 per year. Additional costs are $1,000 a year for insurance and $.50 per person per hour for materials and supplies. Their services would be priced at $10 per hour per person. a. What are fixed costs? b. What are variable costs? c. What is the marginal cost? d. How many student hours would it take to break even ?

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. Time Total Problems Answered 8:00 AM 0 9:00 AM 50 10:00 AM 80 11:00 AM 100 Noon 110 Use the table to answer the following questions. The marginal, or additional, gain from Jake’s first hour of work, from 8:00 AM to 9:00 AM, is problems. The marginal gain from Jake’s third hour of work, from 10:00 AM to 11:00 AM, is problems. Later, the teaching assistant for Jake’s economics course gives him some advice. “Based on past experience,” the teaching assistant says, “working on 25 problems raises a student’s exam score by about the same amount as reading the textbook for 1 hour.” For…

The marginal, or additional, gain from Manuel's first hour of work, from 8:00 AM to 9:00 AM, is problems. The marginal gain from Manuel's third hour of work, from 10:00 AM to 11:00 AM, is problems. Later, the teaching assistant in Manuel's physics course gives him some advice. "Based on past experience," the teaching assistant says, "working on 25 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?
