EXERCISE 6-5 1) sales = variable expenses + fixed expenses + profit $15Q=$12Q + $4200 3Q=$4200 Q=$4200 3 Q=$1400 2) 15X = 12X + $4200 + 0 X = 0.8X+$4200 + 0 0.2X = $4200 X = $4200 0.2 X = $21000 Contribution margin = fixed expenses Unit contribution margin = $4200 0.2 =$21000 Contribution margin ratio= 0.2 $15 =1.33% 3)sales = variable expenses + fixed expenses + profit 15Q=12Q + $4200 3Q=$4200 Q=$4200 3 Q=$21000 fixed expenses contribution margin per unit =$4200 $15 =280 unit
4)break –even point in unit sales =fixed expenses Unit contribution margin =$4200 3 per unit =1400 unit Beak –even point in dollar sales = fixed expenses Contribution margin ratio =$4200 0.2 =$21000
