PREP数学题,关于revenue的,谁帮着看看把
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.
我觉得应该选C啊
条件一可以求出K
然后联合条件二可以求出t
在然后revenue-cost不就是gross profit吗? |
