Part 1: Required a. Relative to the number of students in a single course, is the cost of instruction a fixed or a variable cost? b. Determine the profit, assuming that 20 students attend the course. c. Determine the profit, assuming a 10 percent increase in enrollment (ie., enrollment increases to 22 students). What is the percentage change in profitability? d. Determine the profit, assuming a 10 percent decrease in enrollment (ie., enrollment decreases to 18 students). What is the percentage change in profitability? Explain why a 10 percent shift in enrollment produces more than a 10 percent shift in profitability. Use the term that identifies this phenomenon. course. Required k. Calculate the workbook cost in total and per student, assuming that 18, 20, or 22 students attempt to attend the course. Round your computation to two decimal points. 1. Classify the cost of workbooks as fixed or variable relative to the number of students attending the m. Discuss the risk of holding inventory as it applies to the workbooks. n. Explain how a just-in-time inventory system can reduce the cost and risk of holding inventory. Part 2: The instructor has offered to teach the course for a percentage of tuition fees. Specifically, she wants $300 per person attending the class. Assume that the tuition fee remains at 5700 per student. Required 1. Is the cost of instruction a fixed or a variable cost? B. Determine the profit, assuming that 20 students take the course. h. Determine the profit, assuming a 10 percent increase in enrollment Cie., enrollment increases to 22 students). What is the percentage change in profitability? 1. Determine the profit, assuming a 10 percent decrease in enrollment (i.e., enrollment decreases to 18 students). What is the percentage change in profitability? 1. Explain why a 10 percent change in enrollment produces a proportional 10 percent change in profitability. Part 3: FTS sells a workbook with printed material unique to each course to each student who attends the coure. Any workbooks that are not sold must be destroyed. Prior to the first class, FTS printed 20 copies of the books based on the client's estimate of the number of people who would attend the course. Each workbook costs $30 and is sold to coure participants for $50. This cost includes a roy- alty fee paid to the author and the cost of duplication. Problem 11-25 (cont.)

It offers courses in the clients' offices on the clients' equipment. The only major expense FTS incurs is instructor salaries; it pays instructors $6,000 per course taught. FTS recently agreed to offer a course of instruction to the employees of Novak Incorporated at a price of $700 per student. Novak estimated that 20 students would attend the course. Base your answers on the preceding information, Part 1: Required a. Relative to the number of students in a single course, is the cost of instruction a fixed or a variable cost? b. Determine the profit, assuming that 20 students attend the course. c. Determine the profit, assuming a 10 percent increase in enrollment (ie., enrollment increases to 22 students). What is the percentage change in profitability? d. Determine the profit, assuming a 10 percent decrease in enrollment (i.e., enrollment decreases to 18 students). What is the percentage change in profitability? e. Explain why a 10 percent shift in enrollment produces more than a 10 percent shift in profitability. Use the term that identifies this phenomenon.
