Barlow Company has only 6,600 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 supplier's 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. (Hint: use the DM cost in the table and the cost per pound given in the additional information to calculate how many pounds are used by each product.) 2. Assuming that Barlow has unlimited demand for each of its three products, what is the maximum contribution margin the company can earn when using the 6,600 pounds of raw material on hand? 3. Assuming that Barlow's estimated customer demand is 500 units per product line, what is the maximum contribution margin the company can earn when using the 6,600 pounds of raw material on hand? {See the hint below ifyou need help.) 4. A foreign supplier could furnish Barlow with additional stocks of the raw material at a substantial premium over the usual price.
