EXERCISE 5-18 Missing Data; Basic CVP Concepts [L01, LO9] Fill in the missing amounts in each of the eight case situations below. Each case is independent of the others. (Hint: One way to find the missing amounts would be to prepare a contribution format income statement for each case, enter the known data, and then compute the missing items.) a. Assume that only one product is being sold in each of the four following case situations: Net Operating Contribution Margin Units Sold Fixed Income Expenses per Unit Expenses(Loss) Variable Case Sales $90,000 $170,000 $40,000 $35,000 $82,000 $(12,000) ? $350,000 $15 S6 2 3..20,000 4 $280,000 5,000 $160,000 b. Assume that more than one product is being sold in each of the four following case situations: Net Average Contribution Operating Fixed Income Sales Expenses (Percent) Expenses(Loss) $65,000 Variable Margin Case 40% $60,000 $470,000 80% $90,000 3 4.... $300,000 $90,000 ?$(15,000)
