If the total price of n equally priced shares of a certain stock was $12,000
, what was the price per share of the stock?
1. If the price per share of the stock had been $1 more, the total price of
the n shares would have been $300 more
2. If the price per share of the stock had been $2 less, the total price of
the n shares would have been 5 percent less
答案是D，但一時之間思考有點混亂，所以就有點搞糊塗了
懇請強者解惑<(_ _)>
