Hotco oil burners, designed to be used in asphalt plants, are so efficient that Hotco will sell one to the Clifton
Asphalt plant for no payment other than the cost savings between the total amount the asphalt plant actually
paid for oil using its former burner during the last two years and the total amount it will pay for oil using the
Hotco burner during the next two years. On installation, the plant will make an estimated payment, which will be
adjusted after two years to equal the actual cost savings.
Which of the following, if it occurred, would constitute a disadvantage for Hotco of the plan described above?
(A) Another manufacturer’s introduction to the market of a similarly efficient burner
(B) The Clifton Asphalt plant’s need for more than one new burner
(C) Very poor efficiency in the Clifton Asphalt plant’s old burner
(D) A decrease in the demand for asphalt
(E) A steady increase in the price of oil beginning soon after the new burner is installed
E 选项感觉不对啊,题目说付款是由实际节省下来的钱决定的,如果价钱却高,那么高效率的设备节省的就越多啊。这应该是优势啊。等NN解惑作者: lansere 时间: 2010-4-10 09:59
我觉得:这个burner所能节省下来的油数量是一定的(我们假设现在一年用量是1000仑)(假设油价为2块钱一仑,以前是1块钱一仑)总金额为2×1000=2000块。
而burner的公司是收多少钱呢:between the total amount the asphalt plant actually
paid for oil using its former burner during the last two years and the total amount it will pay for oil using the Hotco burner during the next two years。
这样看,我们假设过去用量是2000仑,过去两年油价是1块钱每仑。那么total amount=1*2000=2000块。
这样一来burner公司的收入就是2000-2000=0!这不就是对他不利了吗?
如果油价没变,公司的收入应该是1*2000-1*1000=1000块
不知道我的理解对不对?作者: xiruihuang 时间: 2010-4-10 21:34
多谢2楼的解释。还有疑问
这个burner所能节省下来的油数量是一定的(我们假设现在一年用量是1000仑)(假设油价为2块钱一仑,以前是1块钱一仑)总金额为2×1000=2000块。’应该算两年的吧,2 x 1000 x 2 =4000
这里该用哪个数减那个数。(我数学还没看), LS的减法收入就变负值了。。。。也就是说只要油涨价就倒贴钱 要是反过来减就多了。 晕了。。。。。。作者: douding 时间: 2010-4-11 01:49
