Problem 13-6

A produce distributor uses 800 packing crates a month, which it purchases at a cost of $10 each. The manager has assigned an annual carrying cost of 35 percent of the purchase price per crate. Ordering costs are $28. Currently the manager orders once a month.

 

How much could the firm save annually in ordering and carrying costs by using the EOQ? (Round intermediate calculations and final answer to 2 decimal places. Omit the "$" sign in your response.)

Problem 13-9

The Friendly Sausage Factory (FSF) can produce hot dogs at a rate of 5,000 per day. FSF supplies hot dogs to local restaurants at a steady rate of 280 per day.

Problem 13-10

A chemical firm produces sodium bisulfate in 100-pound bags. Demand for this product is 30 tons per day. The capacity for producing the product is 50 tons per day. Setup costs $100, and storage and handling costs are $4 per ton a year. The firm operates 200 days a year. (Note: 1 ton = 2,000 pounds.)
