Answer:
1) Break even unit = Fixed cost/Contribution margin per unit = 73800/6 = 12300 Units
Break even sales = 12300*20 = $246000
2) Total contribution margin at break even = Fixed cost = $73800
3) Required unit = (Fixed cost+Desired profit)/Contribution margin per unit = (73800+33600)/6 = 17900 Units
4) Contribution margin income statement
Sales (17900*20) 358000
Variable cost 250600
Contribution margin 107400
Fixed cost 73800
Operating income 33600
5) Margin of safety = 306000-246000 =60000
Margin of safety percentage = 60000/306000 = 19.61%
6) CM ratio = 6/20 = 30%
If sales increase by 96000 then net operating income to increase by (96000*30%) = 28800
