Part 2
Sales Mix Recommendation To the extent allowed by production and
market constraints, the company should produce as much of Product R as
possible. With a single shift yielding 176 hours per month (8 x 22), the
company can produce these units of Product R:
Maximum output of R = = 440 units per month
176 hrs. per mo.
0.4 hrs. per unit

Computation Notes Closing Department Z will eliminate 65% of its insurance
expense and 30% of its miscellaneous office expense. Sales salaries will be
reduced by the amounts paid to the two clerks who will not be replaced. The
office salary will not be eliminated, but it will be reclassified so that one-half will
be reported as sales salary and one-half as office salary.

ANALYSIS
Department Z's avoidable expenses of $181,960 are $6,960 greater than its
revenues of $175,000. This means the company's annual net income would
be $6,960 higher from eliminating Department Z. This analysis suggests
management should probably go ahead with the elimination of the
department as planned.
