21. C&A reports annual sales of $5 million, cost of goods sold of $2 million, inventory of $0.5 million, and net income of $0.75 million. What are C&A’s annual inventory turns and month-of-supply of inventory?

Inventory turn = COGS / Average Inventory = 2/0.5 = 4

Months-of- Supply Inventory= Avg Inventory/ COGS*12 months= (0.5/2)*12=3 months

22. C&A purchases cases of fertilizer for its lawn-care business from a supplier who charges C&A $30 per order and $50 per case. Each case consists of five bags of fertilizer.

How many cases of fertilizer should C&A order from its supplier with each order to minimize the total ordering and holding cost?

40

23. Bakery A uses 80 bags of chocolate chips each year. The chocolate chips are purchased from a supplier for a price of $80 per bag and an ordering cost of $20 per order. Bakery A’s annual inventory holding cost percentage is 40%. If Bakery A chooses an order quantity of 10 bags, what are its ordering and holding costs per year expressed as a percentage of their annual purchasing cost?

Order Size = Demand/no. of orders = 80/10 = 8 bags per order

Annual Ordering Cost = no. of orders x cost per order = 10 x 20 = $200

Annual holding Cost = Average inventory x holding charge x unit cost

Annual holding Cost = (Q/10) x I x C = 200/10 x 0.4 x 80 = $640

Annual Ordering and Holding cost = 200+ 640 = $840

24. Store A uses the newsvendor model to manage its inventory. Demand for its product is normally distributed with a mean of 500 and a standard deviation of 200. Store A purchases the product for $10 each unit and sells each for $30. Inventory is salvaged for $5.What is its expected profit if Store A’s order quantity is 400 units? 13.8 textbook

Expected Profit=Q*(sell price-cost price)
=`400*(30-10)=400*20=**$8,000**

14. Annual Requirement = Weekly Demand x Number of operational weeks

= 600 x 50 = 30,000 Bottles

Number of orders = Annual demand / Order Size

= 30,000 / 500

= 60

Ordering Cost = Number of orders x Ordering cost per order

= 60 x $30

= $1,800

Average Inventory = Lot Size / 2 = 500 / 2 = 250 Bottles

Holding cost per unit = Purchase Price x Holding cost percentage

= $50 x 40% = $20 per unit per annum

Holding cost of average inventory = Average Inventory x Holding cost per unit per annum

= 250 x $20 = $5,000

So, total ordering and holding cost per year when lot size is 500

= $1,800 + $5,000

= $6,800

Answer #1

1. True, since in production levelling, the production is made at constant levels, hence fluctuation in demand levels causes to increase the inventory levels when demand goes down and use up inventory fast enough when demand goes up.

2. False, Companies may be in the same industry but they may have different products, different demand for those products, different country the company is situated in hence the inventory turnover will vary.
