In question 3-65, how do you calculate contribution margin per machine hours?
- Contribution margin / machine hours per unit
- $2.00 / 0.2 = $10.00
In question 3-65, how do you calculate the optimal units per product once you have the contribution margin per machine hour?
- Starting with the products with the highest contribution margin per machine hour, multiply the Total Unit Demand for Next Year by the Machine Hours per Unit.200,000 x 0.20 =40,000 units
- Use the remaining machine hours to calculate the units for remaining products by dividing remaining Machine Hours by Machine Hours per Unit for the remaining products.
- 10,000 ÷ 0.25 = 40,000 units
In question 3-65, when deciding if the overtime is worthwhile to product max units of the third product, what is important to make the decision?

In question 3-46, how are the Variable Manufacturing and Selling Costs calculated for any other combination of units to sell?
- 1. Calculate the Variable Manufacturing and Selling Costs per unit of original units (ie. $198,000 ÷ 36,000 units = $5.50)
- 2. Sum the number of new units.
- 3. Multiple the Variable Manufacturing and Selling Costs per Unit by the new number of units.
In question 3-46, how is the Operating Income calculated?
- 1. Subtract Variable Manufacturing and Selling Costs from Sales to get Contribution Margin. (ie. $360,000 - $198,000 = $162,000)
- 2. Subtract Fixed Costs from Contribution Margin to get Operating Income. (ie. $162,000 - $92,000 = $63,000)
