Lisa bought a house for $70,000 and paid closing costs equal to 2 percent 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?
(A) $2,160
(B) $2,400
(C) $3,600
(D) $3,800
(E) $12,000
答案是B..
這題我很疑惑...我的算法是
買房子:70000+(70000*2%)=71,400
賣房子:82000+(82000*10%)=90,200
所以利潤不就是=90200-71400=18,800
可是為甚麼答案是2400呢??
請問一下~是不是我那邊的計算思考錯誤......
謝謝~!!
