MD Widgets manufactures three different product lines, Model X, Model Y, and Model Z. Considerable market demand exists for all models. The following per unit data apply:
Model X Model YModel Z
Selling price $80 $90 $100
Direct materials $30 30 30
Direct labor ($10/hour) $15 15 20
Variable support costs $5 10 10
($5 per machine-hour)
Fixed support costs 20 20 20
a)For each model, compute the contribution margin per unit. b)For each model, compute the contribution margin per machine-hour. c)If there is excess capacity, which model is the most profitable to produce? Why? d)If there is a machine breakdown, which model is the most profitable to produce? Why? e)How can MD encourage her sales people to promote the more profitable model?
Solution:
MODEL XMODEL YMODEL Z
Selling price $ 80 $ 90 $ 100 Direct materials $ 30 $ 30 $ 30 Direct labor ($10 per hour) $ 15 $ 15 $ 20 Variable support costs ($5 per machine-hour) $ 5 $ 10 $ 10 Total variable cost $ 50 $ 55 $ 60 Fixed support costs $ 20 $ 20 $ 20
Contribution margin per unit = Selling price per unit – Variable cost per unit $ 30$ 35 $ 40 Contribution margin per machine hour
$ 30 $ 18 $ 20
a) The contribution margin per unit for :
Model X = $ 30
Model Y = $ 35

b) The contribution margin per machine-hour for:
Model X = $ 30
Model Y = $ 35
Model Z = $ 40
c) If there is excess capacity, which model is the most profitable to produce? Why? Model Z is more profitable since its contribution margin is greater than the other two models which will result in excess profit. d) If there is a machine breakdown, which model is the most profitable to produce? Why? Model X is more profitable at times of machine break-down since the machine hour required per unit is 1, whereas for the other two models 2 machine hours are required e) How can MD encourage her sales people to promote the more profitable model? By introducing a sales commission depending on the most profitable model, MD can encourage her sales people to promote and sell the most profitable model
