Fifteen years ago, Asher bought four different stocks at their lowest price of the day. He purchased 57 shares of McDoe’s at $78 per share; 78 shares of Younger, Inc. cost him $23 per share; 90 shares of Alfa Goods went for $86 per share; and 64 shares of Hooper, Rex, and Co. had a price of $69 per share. Today, he sold all of his shares in each company. He received $5,313 for McDoe’s, with annual dividends of $12 per year, $2,776 for Younger, Inc, $9,657 for Alfa Goods, and $6,701 for Hooper, Rex, and Co. On which investment did Asher receive the greatest rate of return?
A. McDoe's
B. Younger, Inc
C. Alfa Goods
D. Hooper, Rex, and Co.
I just need help figuring out how to do this problem.
