This is the table from problem $35$ on page $176$ :

New March Demand Forecast $=C-$value $=624$

C$-$value $=\frac{393+670+806}{3}=6232)$

$3.$ Mixed strategy $($allowing inventory and workforce changes from month to month$)$: Find

an optimal plan $($using linear programming$)$ to meet all monthly demands $($assuming back

order not allowed$)$ in order to minimize the total cost including employee hiring and

firing costs and inventory carrying cost

Repeat $(3),$ assuming backlog is allowed at a cost of cP $=$ $$0\mathrm{.}2/$cookie$/$month$.$

make in excel and show all the formular and dont use AL bot for me
