Last year Mrs. Long received $160 in dividends on her shares of Company X stock, all of which she had held for the entire year. If she had had 12 more shares of the stock last year, she would have received $15 more in total annual dividends. How many shares of the stock did she have last year?
(A) - 128 is the answer
$15 in dividends comes from 12 shares
Therefore, $160 in dividends comes from 160*12/15 = 128 shares
