Just before the year ended, a company offered to buy 4,120 units for $14.95 each. X Company had the capacity to produce the additional 4,120 units, but because the special order product was slightly different than the regular product, direct material costs were expected to increase to $2.40 per unit, and some special equipment would have to be rented for a total of $19,000. Sales $1,225,500
Cost of goods sold 521,805
Gross margin $703,695
Selling and administrative costs 153,510
Profit $550,185

Fixed cost of goods sold for the year was $130,935, and fixed selling and administrative costs were $72,885. The special order product has some unique features that will require additional material costs of $0.90 per unit and the rental of special equipment for $3,000. Assume the following fact: regular variable selling and administrative costs include sales commissions equal to 4% of sales, but there will be no sales commissions on the special order. This will cause the special order profit to increase by:

Suppose that fixed costs for a firm in the automobile industry (start-up costs of factories, capital equipment, and so on) are $5 billion and that variable costs are equal to $17,000 per finished automobile. because more firms increase competition in the market, the market price falls as more firms enter an automobile market, or specifically, , where n represents the number of firms in a market. assume that the initial size of the u.s. and the european automobile markets are 300 million and 533 million people, respectively.a. calculate the equilibrium number of firms in the u.s. and european automobile markets without trade.b. what is the equilibrium price of automobiles in the united states and europe if the automobile industry is closed to foreign trade? c. now suppose that the united states decides on free trade in automobiles with europe. the trade agreement with the europeans adds 533 million consumers to the automobile market, in addition to the 300 million in the united states. how many automobile firms will there be in the united states and europe combined? what will be the new equilibrium price of automobiles? d. why are prices in the united states different in (c) and (b)? are consumers better off with free trade? in what ways?
