444 Part Two Planning and Decision Making
residential carpet produced, respectively. The company is currently evaluating its sales mix and the
possibility of expanding its labor force.
Required
1. At the current output level and mix, what is the gross profit (gross margin) for each of the two products,
in total and per square yard? Round total amounts to nearest whole number; round per-yard amounts to
2 decimal places.
2. What is the contribution margin for each of the two products, in total and per square yard? Round total
amounts to nearest whole number; round per-yard amounts for contribution margin to 2 decimal places.
3. Assume that the company has recently conducted a marketing study, which revealed total estimated
weekly demand of 30,000 and 8,000 square yards of commercial and residential carpeting, respectively.
Assume, too, that the company is able to expand its labor force to 4,600 hours per week. (a) What is
the contribution margin per labor hour (to 2 decimal places) for each product? (b) Given your answer
to (a) above, and the labor-hour and product demand constraints, what is the optimum product mix,
on a weekly basis? That is, how many square yards of each product should be produced each week?
(Round answers to nearest whole number.) (c) Generate a graphical solution to this problem, similar to
the solution presented in Exhibit 11.21.
4. What conceptual lesson (take-away) is associated with requirements 1–3 above?
5. What is the primary role of the
product- (or service-) mix problem?
