[求助]请教一道数学题

A jewelry dealer initially offered a bracelet for sale at an asking price that would give a profit to the dealer of 40 percent of the original cost. What was the original cost of the bracelet?

(1) After reducing this asking price by 10 percent, the jewelry dealer sold the bracelet at a profit of $403.

 (2) The jewelry dealer sold the bracelet for $1,953

答案是A

关键是我对题目中的，asking price， original cost， 以及（2）中的sold 佛如1953之间的关系比较迷茫，请明白的战友给解释一下！谢谢

(asking price-original cost)/original cost=40%

(1)90%*asking price-original cost=403

这样两式联立，就可以求出来了。

而（2）中sold的价格不等于就是asking price,所以这个选项没办法求出。

所以选A。
