model. It manufactures two systems, the Star100 and the Star150, which differ in terms of capabilities. The following information is available Costs per Unit Star100 Star150 $ 130 60 30 180 150 80 40 240 S 580 4,000 $ 780 2,000 The average wage rate is $40 per hour. Variable overhead varies with the quantity of direct labor- hours. The plant has a capacity of 20,000 direct labor-hours, but current production uses only 10,000 direct labor-hours. Required a. A nationwide car-sharing service has offered to buy 2,500 Star100 systems and 2,500 Star150 systems if the price is lowered to $400 and $500, respectively, per unit. If Unter accepts the offer, how many direct labor-hours will be required to produce the additional systems? How much will the profit increase (or decrease) if Unter accepts this proposal? Prices on regular sales will remain the same b. Suppose that the car-sharing has offered instead to buy 3,500 each of the two models at $400 and $500, respectively. This customer will purchase the 3,500 units of each model only in an all or-nothing deal. That is, Unter must provide all 3,500 units of each model or none. Unter's management has decided to fill the entire special order for both models. In view of its capacity constraints, Unter will reduce sales to regular customers as needed to fill the special order. How much will the profits change if the order is accepted? Assume that the company cannot increase its production capacity to meet the extra demand c. Answer the question in requirement (b), assuming instead that the plant can work overtime Direct labor costs for the overtime production increase to $60 per hour. Variable overhead costs for overtime production are $10 per hour more than for normal production. Answer questions A, B, and C, but assume that direct material costs are $140 and $155 for the Star100 and Star150 products. Also assume that the normal sales and production volumes are 4,500 and 1,500 for the Star100 and Star150, respectively
