Suppose that the resource base in country x can produce either 100100 units of alpha or 300300 units of beta. similarly, suppose that country y's resource base is capable of producing 100100 units of alpha or 200200 betas. clearly, the opportunity cost of 100100 alphas is lower in

Electronics assembly inc. is a contract manufacturer that assembles consumer electronics for a number of companies. currently, the operations manager is assessing the capacity requirements as input into a bid for a job to assemble cell phones for a major global company. the company would assemble three models of cell phones in the same assembly cell. setup time between the phones is negligible. electronics assembly inc. operates two 8-hour shifts for 275 days per year. cell phone demand forecast (phones/year) processing time (minutes/phone) mars 47,000 19.8 saturn 35,000 20.7 neptune 7,500 16.2 a. calculate total capacity required by line. b. determine the total operating time available. c. calculate the total number of assembly cells. (round up your answer to the next whole number.)

Two products, qi and vh, emerge from a joint process. product qi has been allocated $34,300 of the total joint costs of $55,000. a total of 2,900 units of product qi are produced from the joint process. product qi can be sold at the split-off point for $11 per unit, or it can be processed further for an additional total cost of $10,900 and then sold for $13 per unit. if product qi is processed further and sold, what would be the financial advantage (disadvantage) for the company compared with sale in its unprocessed form directly after the split-off point?
