Part A (Make or Buy decision] Mobile Tech manufactures mobile modems. For several years, the company has purchased 10,000 modems annually from Xeo Ltd at $80 per unit. Due to price increases, company management has asked for an estimate of the cost of manufacturing the modem. The engineering, manufacturing and accounting departments have prepared a report for the management that includes the cost estimate shown below for 10,000 modems. The report states that total costs for 10,000 units are estimated at $957 000, or $95.70 a unit. As the current purchase price is $80 a unit, the report recommends continued purchase of the product. Components (outside purchases) $120 000 Labour 300 000 Manufacturing overhead 450 000 General and administrative overhead 87 000 Total costs $957 000 Although extra staff would need to be hired to accommodate manufacturing modems, no additional equipment, space or supervision would be needed. Variable manufacturing overhead will make up 100%.of direct labour cost. General and administrative overhead, which is a fixed cost, is applied at 10 per cent of the total cost of material (or components), labour and manufacturing overhead.
