Answer:
The Academic Company mixes and bottles a high-energy beverage in various container
types and sizes for college students. The aggregate forecast for the next four quarters (1
year) in thousands of gallons is as follows:
Table 1
Academic's management makes the following assumptions:
Each employee works 550 standard hours of regular time each quarter.
On average, it takes 27 hours to produce and package 1 unit (1,000 gallons).
Regular-time labor costs $6.00/hour; overtime labor costs $9.00/hour.
Inventory-holding cost is approximately $4.50/unit (1,000 gallons) per quarter based
upon the ending inventory per quarter.
Because of extremely hot weather, there is no beginning inventory available to start
Quarter 1.
Management wants a constant work force (no hiring or firing).
Managers have also decided to always round up the number of employees needed to
the next whole integer, i.e., 37.2 yields 38 employees.
