Brian purchased 10 shares of an aggressive growth mutual fund at $90 per share, for a total of $900, 7 years ago. Today he sold all 10 shares for $4,500. What was his average annual compound rate of return on this investment before tax?
$514 give or take. I could be wrong so you might want some confirmation on my answer before putting it on your test or what ever you need it for because i'm only in Middle School.
