Total fixed costs = \$408,000. (1) \$.50X = \$.33X + \$408,000 \$.17X = \$408,000 X = 2,400,000 units (2) 2,400,000 X \$.50 = \$1,200,000 (c) Contribution margin ratio = (\$.50 – \$.33) ÷ \$.50 = 34% (or 1 – .66) Margin of safety ratio = (\$1,800,000 – \$1,200,000) ÷ \$1,800,000 = 33% (rounded) PROBLEM 6-2A (Continued) (d) Required sales X = | \$408,000 + \$238,000 | = \$1,900,000 | | .34 | | BYP 6-3 (a) Sweeteners and packaging are a variable cost to Coca-Cola because their use is directly proportional to the amount of product produced.
