: of the purchase price. Later Lisa sold the house for $82,000 and paid a
: broker's commission equal to 10 percent of the selling price. What was Lisa's
: profit from the two transactions?

: (B) $2,400
: (C) $3,600
: (D) $3,800
: (E) $12,000
: ans: B
: 可以请教一下这题吗?
: 谢谢!
成本: 70,000*(1+2%)=71,400
售价: 82,000
佣金: 82,000*10% = 8,200
利润= 82,000-8,200-71,400=2,400

1F：推 PINKENVI:为啥是(1+2%)? 题目不是说eaual to 2 percent of the 08/12 21:07
2F：→ PINKENVI:purchase price? 08/12 21:08
3F：→ catspace:注意罗! 是买价"之外" 再加上等同买价2%的费用 08/12 21:19
4F：→ catspace:那2%是不包含在70,000里面的唷 老板说要另外算! 08/12 21:20
5F：推 PINKENVI:哪里有之外这个解释阿?看不太出来耶... 08/12 21:40
6F：→ catspace:Lisa bought..."and" paid... "and" is the key point 08/12 21:45
7F：→ catspace:"and" means "besides" 08/12 21:46
8F：→ catspace:因为2%费用这句话是接在$70,000之後 句意就是等同额外的 08/12 21:48
9F：推 PINKENVI:谢谢你唷!!!! ^_^ 08/12 21:48
