An office supply store open five days a week must determine the best inventory policy for boxes of copier paper. Weekly demand is nearly
constant at 210 boxes. When orders are placed, the entire shipment arrives at once. The cost per box is $29, and the inventory holding cost
is 33%. Orders are placed at a cost of $43 each, including preparation time and communication charges, and the lead time is two days. (Assume
the store operates 52 weeks per year.)
(a) Find the optimal order quantity. (Round your answer to the nearest whole number.)
(b) What is the total annual cost (in dollars)? (Round your answer to two decimal places.)

(c) What is the reorder point?

1. What is the EOQ?
Please include/fill the table and solve for EOQ.
Thank you so much!
A local artisan uses supplies purchased from an overseas supplier. The owner believes the assumptions of the EOQ model are met reasonably well. Minimization of inventory costs is her objective. Relevant data, from the files of the craft firm, are annual demand (D) = 150 units, ordering cost (S) = $42 per order, and holding cost (H) = $4 per unit per year.
a. How many should she order at one time?
b. How many times per year will she replenish her inventory of this material?
c. What will be the total annual inventory costs associated with this material?
d. If she discovered that the carrying cost had been overstated, and was in reality only $1 per unit per year, what is the corrected value of EOQ?

The purchase price per package is $53. Which of the following statements is true of Allianz's EOQ system costs? O At EOQ, the annual relevant ordering costs is exactly the half of annual relevant carrying costs. O At EOQ, the annual relevant carrying costs is exactly the half of the annual relevant total costs. O At EOQ, the annual relevant carrying costs is higher than the annual relevant ordering costs.

Daily use of cash register tape averages 10 rolls. Usage appears normally distributed with a standard deviation of 2 rolls per day. The cost of ordering tape is $1 per order, and carrying costs are 40 cents per roll a year. Lead-time is three days. a) Ignoring the demand uncertainty (i.e., looking only at average values), find the economic order quantity (EOQ) and the reorder point (ROP). b) Consider now the uncertainty.
