For Manufacturer M, the cost C of producing x units of its product per month is given by C = kx + t, where C is in dollars and k and t are constants.Last month, if Manufacturer M produced 1,000 units of its product and sold all the units for k + 60 dollars each, what was Manufacturer M's gross profit on the 1,000 units?



(1)Last month, Manufacturer M's revenue from the sale of the 1,000 units was $150,000.



(2)Manufacturer M's cost of producing 500 units in a month is $45,000 less than its cost of producing 1,000 units in a month.

--------------------------------------------------------------------------------------------------------------------------------------------------------【答案】E

【思路】已知x=1000 毛利 = 銷售額 – 銷售成本 = 1000
(k+60) – (1000k+t) => 6000-t
(1) Revenue = Gross Profit – Expense，無法得知營業費用所以無法求出毛利←選項(1)不成立

(2) 由此條件可得知500k+t+45000 = 1000k+t 可求出k但無法求出t←選項(2)不成立

(1) + (2) 兩個條件合併仍無法求出t ←選項(1) + (2)不成立
revenue 就是价格乘以数量吧?不用加费用吧?查了wiki 上面说 Revenue may refer to business income in general, or it may refer to the amount, in a monetary unit, received during a period of time, as in "Last year, Company X had revenue of $42 million." Profits or net income generally imply total revenue minus total expenses in a given period 上面很清楚的说利润或者是近利润才减费用的吧...求NN证实

应该选C吧...

选e 因为另个条件和起来还是求不出t是多少

哦...对对...
那到底看见revenue用不用减去那个费用啊...

revenue是总销售额，是价格X销售数量,不用减费用的，revenue减去费用（cost）是利润（profit）
