What is the financial advantage (disadvantage) of closing the plant for the two-month period? d. Should Andretti close the plant for two months? 5. An outside manufacturer offered to produce 60,000 Daks and ship them directly to Andretti's customers. If Andretti Company accepts this offer, the facilities it uses to produce Daks would be idle; however, fixed manufacturing overhead costs would be reduced by 75%.
