In Problem $18,$ the Dynaco Company has found that if more than three units $($average$)$ are waiting to be processed at any one workstation, then too much money is being tied up in work$-$inprocess inventory $($i$.$e$.,$ units waiting to be processed$).$ The company estimates that $($on average$)$ each unit waiting to be processed costs $$50$ per day. Alternatively, operating a third press would cost $$150$ per day. Should the company operate a third press at this workstation?
