OG11-98题

98. 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?

b/c the unit price of oil is higher than before, even though the machine uses less amount of oil than did the old machine, its total oil cost will still be quite high.

Hence, E is the correct answer

最后一句话,说的是安装好以后, 工厂将付出2年后实际节省的钱给HOTCO公司,油价单价上升,由于HOTCO公司的高效机器节省的油多,节省的油多,由于油价高了, 节省的钱也多了, 那么HOTCO公司将得到工厂给他的更多的钱. 我的理解对吗? 

Not true, they will save certain amount of oil, but since the unit price is high, they will end up saving not too much money. Hence, HOTCO公司 will get less money in terms of saving as a result .

H要的钱是：老油炉使用时油料的花费－新油炉使用时油料的花费

如果新油炉使用的油料额成本上升，那么作为减数，减数增加，余数减少

因为被减数是恒定的，是两年前既成事实的数字。

On installation, the plant will make an estimated payment, which will be adjusted after two years to equal the actual cost savings.

这句话是什么意思？特别是黄色高亮的那部分。

安装后，工厂将预先估计一下开支，预估的开支将在两年后调整成等于实际节约的成本。
