She wants to double the number of shares she owns. About how many shares of stock should ms. garlik buy?
This is a multiple choice problem with the answers being
a. 500 shares
b. 350 shares
c. 300 shares
d. 250 shares
I selected d. 250 shares but my teacher said that was wrong. He said the correct answer is a. 500 shares. I said she already has 250 so she would only need to buy 250 to double. Which is the correct answer and why?

500 is the correct answer, I will explain: Take the question another way, eg: She want's to buy double the shares she own's, she already own's 250 so if she wanted double that, the answer would be 500. I think this is a bit of a trick question, designed to be a bit harder than usual to test your capabilitie's, don't worry, keep studying and you will get there in the end. If you have any further problem's don't be shy to ask again, I am AnneW GOOD LUCK.
