Widget Co. has the following data available relative to its investment in materials:
| Number of units of material used annually |
20,000 |
| Number of workdays in a year |
|
250 |
| Cost of placing an order |
|
$20 |
| Annual carrying cost per unit of inventory |
$5 |
Requirements:
1. Compute the economic order quantity (please show your work).
EOQ= 2*20*20000/5=160,000 Square which is = 400
2. Give some examples of order costs and carrying costs.
Order costs: Purchase order, processing supplier's invoices, documentation costs, cost of inspection of receiving batches and making payment to suppliers
Carrying costs: Warehouse rent,Spoilage costs, taxes, inventory and insurance premium
3. Using the above data, compute the order size that results in the minimum total order and carrying cost by completing the following table.
| Order Size |

4. If the company requires a safety stock of 200 units and has an anticipated lead time of 5 days, what is the order point (please show your work)?
(1/2*400) + 200 = Safty stock required is 400

Deliverables
1. Record the events in the general journal
2. Post the appropriate entries to the T-accounts, identifying each entry by letter. Determine the ending account balances, assuming that the beginning balances were zero.
3. Add the costs of the unfinished houses, and show that this total amount equals the ending balances in the Work in process inventory account.
