Required:
1. What is the quarterly break-even point in units sold and in sales dollars?
2.	Without resorting to computations, calculate the total contribution margin at the break-even point.
3.	How many units would have to be sold each quarter to earn a target profit of $80,000? Use the formula method.
4.	Refer to the original data. Compute the company's margin of safety for the quarter in both dollar and percentage terms. (Round "Percentage" answer to 1 decimal place, (i.e., 0.123 should be considered as 12.3%).)
5.	What is the company's CM ratio? If quarterly sales increase by $40,000 and there is no change in fixed expenses, by how much would you expect quarterly net operating income to increase? (Do not prepare an income statement; use the CM ratio to compute your answer.)
