Marvin Corporation manufactures both an automatic and a manual household dehumidifier. Because of limited demand, for several years production has been at 80% of estimated capacity, which is thought to be limited by the number of machine hours available. At current operations levels, a profit analysis for each product line shows the following:

Per-unit Data

Sales price $350 $150

Production Costs:

Direct material $65 $32

Direct labor 35 25

Variable manufacuring overhead 68 16

Management wants to make use of the company's current excess capacity by increasing production. Each unit of the automatic model requires 2.5 machine hours; the manual model requires 1 machine hour per unit.

REQUIRED

a. Assume that sufficient units of either product can be sold at current prices to utilize exisiting capacity fully and that fixed costs will not be affected.

1. To which product should the excess capacity be devoted if the decision basis is maximization of contribution margin per unit of product?

2. Prepare an analysis showing which product line should be emphasized if the firm's net income is the decision basis.

3. What general decision guideline applies in this situation?

b. Suppose the excess capacity represents 10,000 machine hours, which can be used to makes 4,000 automatic units or 10,000 manual units or any proportionate combination. The only market available for these extra units is a foreign market in which the sales price must be reduced by 20% and in which no more than 6,000 units of either model can be sold. All costs will remain the same excpet that the sales commission of 10% (included in the variable operating expense) will be avoided. Prepare an analysis showing which product should be emphasized and the effect on the firm's net income.

c. Assume that the excess capacity can be used as indicated in requirement (b) and that the firm's market research department believes that the production available from using the excess capacity exclusively on either model can be sold in the domestic market at regular prices if a promotion campaign costing $225,000 is undertaken for the automatic model or $235,000 for the manual model. Prepare an analysis indicating for which product the campaign should be undertaken.
