Barlow Company manufactures three productsA, B, and C. The selling price, variable costs, and contribution margin for one unit of each product follow:

	Product
A	B	C
Selling price	$ 160	$ 270	$ 210
Variable expenses:
Direct materials	16	80	24
Other variable expenses	108	90	144
Total variable expenses	124	170	168
Contribution margin	$ 36	$ 100	$ 42
Contribution margin ratio	23%	37%	20%

The same raw material is used in all three products. Barlow Company has only 5,700 pounds of raw material on hand and will not be able to obtain any more of it for several weeks due to a strike in its suppliers plant. Management is trying to decide which product(s) to concentrate on next week in filling its backlog of orders. The material costs $8 per pound.

Required:

1. Calculate the contribution margin per pound of the constraining resource for each product.
2. Assuming Barlow has unlimited demand for each of its three products, what is the maximum contribution margin the company can earn when using the 5,700 pounds of raw material on hand?
3. Assuming Barlows estimated customer demand is 500 units per product line, what is the maximum contribution margin the company can earn when using the 5,700 pounds of raw material on hand?
4. A foreign supplier could furnish Barlow with additional stocks of the raw material at a substantial premium over the usual price. Assuming Barlows estimated customer demand is 500 units per product line and the company has used its 5,700 pounds of raw material in an optimal fashion, what is the highest price Barlow Company should be willing to pay for an additional pound of materials?
