ABC Apple Juice Company produces and markets fresh fruit juice. During the apple harvest season, trucks bring apples from the fields to the process plant during a workday that runs long hours from 7AM. On peak days, approximately 3,000 kg of apples are trucked in per hour. Trucks dump their contents in a holding bin with a storage capacity of 9,000 kg. When the bin is full, incoming trucks must wait until it has sufficient available space. A conveyor moves apples from bin to the processing plant. The plant is configured to process apples at the rate of 2,000 kg per hour. Trucks arrive uniformly between 7:00AM to 5:00PM. Each truck holds about 1,000 kg of apples. The truck drivers are paid at the rate of $10 per hour. As ABC makes fresh juice, it does not store apples. Processing plant starts at 10:00AM and ends when all the apples received during the day have been processed. It takes 2 hours to clean the empty plant that must be kept ready for the next day production. Trucks are owned and operated by ABC. The peak periods consists of 30 days during the harvest season.

A firm is faced with the attractive situation in which it can obtain immediate delivery of an item it stocks for retail sale. The firm has therefore not bothered to order the item in any systematic way. However, recently profits have been squeezed due to increasing competitive pressures, and the firm has retained a management consultant to study its inventory management. The consultant has determined that the various costs associated with making an order for the item stocked are approximately $90 per order. She has also determined that the costs of carrying the item in inventory amount to approximately $20 per unit per year (primarily direct storage costs and foregone profit on investment in inventory). Demand for the item is reasonably constant over time, and the forecast is for 1,600 units per year. When an order is placed for the item, the entire order is immediately delivered to the firm by the supplier.

Accounts Receivable (AR) receives an average of 800 payments per week. There is an average of 400 checks waiting to be deposited. Assume that the checks coming in are either small or large. Small checks are for an average of $600 and large checks are for an average of $4,000. 25% of the checks coming in are large with the rest being small. Currently, no distinction is made between the large and small checks. As a result, 25% of the checks waiting to be processed are large. A proposed change in the existing process will result in a re-allocation of resources. As a consequence, large checks will wait an average of 0.3 weeks while small checks will wait an average of 0.8 weeks before being processed. What is the change in the total value of checks held as inventory by AR (in terms of dollars) after the new process is introduced.

a. Decrease by $1,600

 b. Decrease by $8,000

c. Decrease by $12,000

d. Increase by $58,000

e. Decrease by $52,000
