III. Problem #2 - Constrained Resources (15 points) Silvio Enterprises produces three products, with costs and selling prices as follows: Model B3 Model D7 Model F5 100% $ 42.00 $ 34,00 100% 100% Selling price per unit $ 50.00 $ 36,00 $ 14.00 Variable costs per unit 45% $ 18.00 72% S 12.00 40% Contribution margin per unit S 24.00 55% $ 2200 60% 28% Each product requires a certain number of minutes on the drill press. There is only one drill press available, so it is the constraint for this product. Model D7 requires 2 minutes of drill press time, Model B3 requires 1 minute of drill press time, and Model F5 requires 7 minutes of drill press time. a. Calculate the Contribution Margin for each product b. Calculate the Contribution Margin er minute for each product c.
