Be sure to check the list of worksheet functions that are needed for the homework assignments, to see which new functions (if any) might help with this one.
For a quick way to copy homework problem data into your homework solution, see "Avoid retyping homework problem data."
Since macros are not permitted in this homework assignment, be certain that your workbook has no macros.
Remember that some problems are slight extensions of what we show you in demonstrations and the session notes, and some problems are somewhat ambiguous. This is intended to parallel what you'll frequently encounter at work. If you feel a bit confused, there are some things you can do to help clarify things.
Before attempting this homework, you might find it helpful to read about:

Worksheet Functions

Numbers at the left in square brackets indicate point values.

11.1 [20]

Kansas Fried Chicken logo The regional warehouse of a fast food chain, Kansas Fried Chicken, orders buckets for its fried chicken every four months. Demand for fried chicken is constant, requiring 160 cases per month. A case of buckets costs $21.20. Assume that inventory is 0 on December 31, and that the first order is received on January 1. Assume also that you receive each new order at exactly the moment that your inventory is depleted.

(a) [2]

Find the inventory of chicken buckets, measured in cases, at the beginning of each month of a twelve-month year. Your result should be a single 1x12 range.

(b) [3]

Find the maximum inventory (in cases). Your result should be a single cell.

Find the average inventory (in cases) over one order cycle. Your result should be a single cell.

(d) [5]

Find the average annual inventory (in cases). Your result should be a single cell.

(e) [5]

Find the average dollar investment required to maintain the inventory. Your result should be a single cell.

11.2 [40]

Kansas Fried Chicken estimates that it spends $89 when it places an order for chicken buckets, and that the cost of maintaining inventory is approximately 26% of its average inventory investment on an annual basis.

(a) [8]

Compute the economic order quantity in cases. Your result should be a single cell.

(b) [8]

How many orders are required annually (on average)? Your result should be a single cell.

If KFC orders buckets in this way, what are annual ordering costs? Your result should be a single cell.

(d) [8]

If KFC orders buckets in this way, what are annual holding costs? Your result should be a single cell.

(e) [8]

How much is saved annually compared to the old ordering cycle used in Problem 11.1? Your result should be a single cell.

11.3 [40]

KFC has negotiated a deal with its paper supplier which gives KFC a quantity discount on its per order purchases of chicken buckets. The price schedule below shows the price per case of buckets as a function of the number of cases ordered:

Quantity	Price
1-399	$21.00
400-1199	$18.00
1200 or more	$17.30

(a) [20]

Assuming that the cost to order is $89 and that the cost to hold is 26% per year, compute the optimum order quantity. Note that the optimum order quantity might be different from the Economic Order Quantity. Your result should be a single cell.

(b) [20]

How much would be lost or saved annually by each discount option compared to the EOQ strategy for each price range? Your result should be a single 3x1 range.
