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.) Required: Assume that only one product is being sold in each of the four following case situations: Case #2 Case #3 20,000 or Case #1 8,500 $ 221,000 144,500 89,000 Case #4 5,000 130,000 $ 315,000 Unit sold Sales Variable expenses Fixed expenses Net operating income (loss) Contribution margin per unit $ 200,000| 91,000 (51,000) $ 162,000 33,000 $ 13s $ 172,000 137 $ b. Assume that more than one product is being sold in each of the four following case situations: Case #3 Case #1 $ 445,000 Sales Case #2 $ 192,000 122,880 64,000 | $ Case #4 299,000 98,670 Variable expenses Fixed expenses Net operating income (loss) Average contribution margin ratio (percent) $ $ 52,100 38% 473,000 100,480 81% $ (20,670)
