$5$ years ago Clarissa purchased shares in a certain mutual fund at Net Asset Value $($NAV$)$ of $$62.$ She reinvested her dividends into the fund, and today she has $7\mathrm{.}9\%$ more shares than when she started. If the fund's NAV has increased by $27\mathrm{.}5\%$ since her purchase, compute the rate of return on her investment if she sells her shares today.

Round your answer to the nearest tenth of a percent.
