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: a. Assume that only one product is being sold in each of the four following case situations: Case #1 Case #2 Case #3 Case #4 4,100 $110,700 8,800 19,000 Unit sold Sales Variable expenses Fixed expenses Net operating income (loss) Contribution margin per unit $255,200 377,000 158,400 209,000 97,000 164,000 74,000 $ 18,000 110,000 (41,200) 14 $ 10 b. Assume that more than one product is being sold in each of the four following case situations: Case #1 Case #2 Case #3 Case #4 Sales Variable expenses Fixed expenses Net operating income (loss) Average contribution margin ratio (percent) $452,000 195,000 118,950 54,000 $ 302,000 93,620 473,000 S55,760 38% $72,160 (15,620) 7790
