Total sales 480,000 100% 230,000 47.9% 250,000 52.1%
Variable costs 307,200 100% 138,000 44.9% 169,200 55.1%
Contribution margin 172,800 100% 92,000 53.2% 80,800 46.8%
Traceable fixed 100,800 100% 52,500 52.1% 48,300 47.9%
Segment income 72,000 100% 39,500 54.9% 32,500 45.1%
Common fixed 62,400 100%
Net income 9,600 100%
North's total sales = $92,000 / 40% = $230,000
South's total sales = $480,000 - $230,000 = $250,000
South's contribution margin = $172,800 - $92,000 = $80,800
Total segment income = common fixed + net income = $62,400 + $9,600 = $72,000
