Answer the following questions based on Three Jay's Case.

$1.$ Compute the setup cost that is currently used by Three Jays. Show the computation details. $($Hint: Consider the admin cost, production preparation cost, size changeover cost, and cleaning cost. Ensure that you compute the cost in $ per setup.$)10$ points.

$2.$ Compute the holding cost for the different jams in $ $/$ unit $/$ per year. $10$ points.

$3.$ Update the EOQ quantities for all the types of Jams based on $2012$ demand data. What is the percentage change in EOQ values from the existing ones which are based on the $2010$ demand? $($Use yearly demand data for the computations in Exhibit $5).25$ points.

$4.$ Recompute the setup cost and the holding costs based on only idle time of hourly line workers only $($for setup$)$ and the opportunity cost of investing in marketing, and other expenses only $($for holding cost; do not account for cost of capital$)?20$ points.

$5.$ Recompute the EOQ quantities based on the revised setup and holding cost. What is the percentage change from current values? $25$ points.
