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 date, and then compute the missing items.) Required: a. Assume that only one product is being sold in each of the four following case situations: Case #2 Case #1 8,100 Case #3 19,600 Unit sold Case #4 4,800 $ 168,000 $ 429,000 274,400 Sales Variable expenses Fixed expenses Net operating income (loss) Contribution margin per unit 234,900 $ 121,500 98,000 $ $ 162,000 95,400 $ 18$ 80,000 16,000 98,400 $ 9 b. Assume that more than one product is being sold in each of the four following case situations: Sales Variable expenses Fixed expenses Net operating income (loss) Contribution margin ratio (percent) Case #1 Case #2 $ 442,000 $ 193,000 121,590 57.000 $ 49,960 Case #3 Case #4 $ 294,000 73,500 475.000 $ 61,690$ 3,500 77% 38%
