The following table contains data about the inventory for $2$ items at Jones Corporation for

the fiscal year that just ended.

a$.$ The item unit cost was as follows:

Item $1=$$$67\mathrm{.}00,$ Item $2=$$$14\mathrm{.}00$

Compute the $(1)$ average unit inventory for each item. Then compute the dollar values

of $(2)$ annual sales and $(3)$ average inventory for each item.

b$.$ Compute inventory turnover for each item using dollar values of annual sales and

average inventory. Also, compute the total inventory turnover for the aggregate

inventory for Jones Corporation. Is the total inventory turnover a sum of inventory

turnovers for the two items?

c$.$ Suppose Jones Corporation determined that its annual inventory holding cost $=23\%$ of

inventory value. Compute the average inventory holding cost for each item.

d$.$ Suppose Jones Corporation believes that in the upcoming year, the rate of sales

expected for each of the $2$ items is as follows:

Item $1=14,200$ units per week

Item $2=43,900$ units per week

Compute the weeks of supply for each item. Which unit inventory should you use for

weeks of supply? Why?
