※ 引述《shaoying (我的舌头竟然淤青)》之铭言：
: 153. 15587-!-item-!-187;#058&010762
: At a certain supplier, a machine of type A costs $20,000
: and a machine of type B costs $50,000. Each machine can
: be purchased by making a 20 percent down payment and repaying
: the remainder of the cost and the finance charges over a
: period of time. If the finance charges are equal to 40 percent
: of the remainder of the cost, how much less would 2 machines of
: type A cost than 1 machine of type B under this arrangement?
题目大致上是说 可以分期付款 先付头期款20%
接下来的钱利息是40%去算 问买两台A跟买一台B的价钱差多少
A头期款:(20,000*2)*20% = 8000
A尾款:(40,000-8000)*1.4= 44,800
B头期款:50,000*20% = 10,000
B尾款:(50,000-10,000)*1.4 = 56,000
在把两个的头起款跟尾款相加就等於总共要付的钱
相减就可以得到两个的差是13,200
我想你应该是题目看不太懂吧 计算不难的
: (A) $10,000
: (B) $11,200
: (C) $12,000
: (D) $12,800
: (E) $13,200
: Ans:E；我连题目都不太晓得在干麻，拜托帮忙了，谢谢！
