Given the following information set up the problem in a transportation table and solve for the minimum$-$cost plan. Solve by modifying textbook Table $11\mathrm{.}6.$

$\backslash$table$[[,$PERIOD$],[$Demand$,1,2,3],[$Capacity$,550,700,750],[,$ Regular,$500,500,500],[,$ Overtime,$50,50,50],[,$ Subcontract,$120,120,100],[$Beginning inventory,$100,,],[$Costs$,$$$60$ per unit,,$],[,$ Regular time,$$80$ per unit,,$],[$Overtime$,$$$90$ per unit,,$],[$Subcontract$,$$$1$ per unit per month,,$],[$Inventory carrying cost,$$3$ per unit per month,,$],[$Back$-$order cost,,,$]]$

Suppose that regular$-$time capacity will be reduced to $440$ units in period $3$ to accommodate a companywide safety inspection of equipment. What will the additional cost of the optimal plan be$?$

Additional cost
