Each morning, a supplier drops off bags of these products. We can buy up to 200 bags of avocados and up to 175 bags of artichokes each morning. We resell the bags to customers throughout the day. The contribution margin of avocados is $15/bag; the contribution margin of artichokes is $20/bag. We sell at least twice as many bags of avocados as we do artichokes.

The mechanics do not have room or the capital to store all the parts they may need so they place orders multiple times during the day. Exhausting Enterprises has a small fleet of delivery vans to make deliveries. Focusing on alternators, lead time for Exhausting Enterprises to receive more alternators from their supplier is 2 days. Alternators experience an average daily demand of 0.8 and follow a Poisson distribution. At the start of the day, Exhausting Enterprises has a backorder of 1 alternator and none in-stock. There are 4 alternators on the way. How many alternators will Exhausting Enterprises need to order if their order-up-to level is set to 7? What is the average on-hand inventory and on-order inventory for alternators? What is the probability of alternators being in-stock?arrow_forward

- Mancuso's Music Store is a small business that sells instruments, books, stands, and other music-related products. The owner always likes to have extra music stands in storage in case a large order arrives suddenly – typically 2 weeks' worth of sales. When an order is placed, the delivery takes 5 business days to arive. The owner has studied working capital management and estimates that the economic order quantity for music stands is 1500 for each time an order is placed. The fixed cost of an order is $210 and the carrying cost per stand per year is $1.70. How many music stands will the store have in stock immediately after a shipment arrives? Assume the store is closed on Sundays (a 6-day business week), holidays, and a few vacation days, so that the store has 300 business days per year.

Together, with help from vendors, they think they can adequately estimate demand, fixed costs, revenues, and variable cost per bag of lettuce. They think a largely manual process will have monthly fixed costs of $40,000 and variable costs of $2.00 per bag. A more mechanized process will have fixed costs of $72,000 per month with variable costs of $1.25 per bag.
