At the beginning of last year, you invested $4000 in 80 shares of ABC company. During the year ABC paid $5 dividends per share. At the end of the year, you sold the 80 shares for $59 a share. Compute your holding period return and state how much was due to price appreciation and how huch was due to dividend income.

这道题的HPR应该是 [（80*$59）+($5*80) ] /4000 对吧？ 但后面两个问  how much was due to price appreciation and how huch was due to dividend income 是什么呢？
