The instructor has offered to teach the course for a percentage of tuition fees. Specifically, she wants $210 per person attending the class. Assume that the tuition fee remains at $490 per student.

Required:

a. Is the cost of instruction a fixed or a variable cost?
b. Determine the profit, assuming that 20 students take the course.
c. Determine the profit, assuming a 10 percent increase in enrollment i. e., 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?
e. Explain why a 10 percent change in enrollment produces a proportional 10 percent change in profitability

Aprice ceiling is “binding” if the price ceiling is set below the equilibrium price. suppose that the equilibrium price is $5. if a price ceiling is set at $6, this will not affect the market in any way since $5 remains a legally allowable price (since $5 < $6). a price ceiling of $6 is called a “non-binding” price ceiling. on the other hand, if the price ceiling is set at $4, the price ceiling is “binding” because the natural equilibrium price is $5 but that is no longer allowed. what happens when there is a binding price ceiling? at a price below the equilibrium price, quantity demanded exceeds quantity supplied. there is a shortage. normally, price increases eliminate shortages by increasing quantity supplied and decreasing quantity demanded. in this case, however, price increases are not allowed past the price ceiling. we therefore predict that the observed market price will be right at the price ceiling and there will be a permanent shortage. the observed quantity bought and sold will be dictated by the quantity supplied at the price ceiling. although consumers would like to buy more, there are no more units for sale
