$15$ years ago, I purchased $189$ shares of a stock worth $$16\mathrm{.}35$ per share. There was a $2$:$1$

split, a $4$:$1$ split, and a $3$:$1$ split during that time period. Today the stock is worth $$2\mathrm{.}85$ per

share. If the dividend yield was on average $11\%$ during the last $15$ years, what was the total

rate of return?
