6.34 continued. c. Alternative B Sales ............................................................................ $2,250,000 Variable Costs (.95)($1,250,000) ................................. 1,187,500 Total Contribution Margin ............................................. $ 1,062,500 Contribution Margin Ratio = $1,062,500/$2,250,000 = .47 Breakeven Point in Dollars = $1,300,000*/.47 = $2,765,957. *$1,300,000 = $1,000,000 + $300,000. d. The company should choose the alternative that yields the greatest profit in the projected relevant range, probably Alternative A. 6.35 (Shout Company; CVP analysis with semifixed [step] costs.) a. Breakeven points: Breakeven Unit Sales = Breakeven Units (Level 1) = $40,000/($20 – $12) = 5,000 Units Breakeven Units (Level 2) = $80,000/($20 – $12) = 10,000 Units Breakeven Units (Level 3) = $100,000/($20 – $12) = 12,500 Units Levels 2 and 3 provide a profit for the entire range of activity, hence, there is no breakeven point for either of these levels. b. Profit: Level 1 (10,000 units): (10,000 X $8) – $40,000 = $40,000 Level 2 (25,000 units): (25,000 X $8) – $80,000 = $120,000 Level 3 (40,000 units): (40,000 X $8) – $100,000 = $220,000 Profit is optimal at Level 3.

6.36 c. continued. Level 2: Profit = ($50 – $30)20,000 units + ($50 – $42)16,000 units – $164,000 = $364,000. The company is more profitable at Level 2 with 36,000 units. 6.37 (Kids Education Center; CVP analysis with semifixed costs.) a. Operating Profit = [($380 – $80)30 students] – [$1,200 X 6 teachers] – $900 = $9,000 – $7,200 – $900 = $900. b. Operating Profit = ($380 – $80) X – $1,200 Q – $900 where X = number of students and Q = number of teachers. ( Note : An incorrect but common method is to substitute the ratio X /6 for Q and solve for X . This gives 9 students, but it assumes 1 1/2 teachers are employed.) This part demonstrates the impact of step costs on cost-volume-profit analysis. 0 - 6 students: Operating Profit = $300 X – ($1,200 X 1) – $900 X = = 7
