The company has seen monthly demand from its retailers for its electronic and battery-operated detectors rise to 20,000 and 10,000 respectively, and Acme wishes to continue meeting demand. Acme's production process involves three departments: Fabrication, Assembly, and Shipping. The relevant quantitative data on production and prices are summarized below. Department Fabrication Assembly Shipping Variable cost/ unit Retail Price Monthly Hours Hours / Unit Hours / Unit Available (Electronic) (Battery) 2400 0.15 0.10 4200 0.20 0.20 2000 0.10 0.15 $17.00 $16.00 $30.00 $28.00 The company also has the option to obtain additional units from a subcontractor, who has offered to supply up to 20,000 units per month in any combination of electric and battery operated models, at a charge of $20.00 per unit. For this price, the subcontractor will test and ship its models directly to the retailers without using Acme's production process Determine how the manufacturer should allocate its in-house capacity and how it should utilize the subcontractor.
