Re: [計量] Prep Test2(ps)153題
※ 引述《shaoying (我的舌頭竟然淤青)》之銘言：
: 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?
題目大致上是說 可以分期付款 先付頭期款20%
接下來的錢利息是40%去算 問買兩台A跟買一台B的價錢差多少
A頭期款:(20,000*2)*20% = 8000
A尾款:(40,000-8000)*1.4= 44,800
B頭期款:50,000*20% = 10,000
B尾款:(50,000-10,000)*1.4 = 56,000
在把兩個的頭起款跟尾款相加就等於總共要付的錢
相減就可以得到兩個的差是13,200
我想你應該是題目看不太懂吧 計算不難的
: (A) $10,000
: (B) $11,200
: (C) $12,000
: (D) $12,800
: (E) $13,200
: Ans:E；我連題目都不太曉得在幹麻，拜託幫忙了，謝謝！
