15 years ago, I purchased 164 shares of a stock worth \$12.11 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 \$2.2 per share. If the dividend yield was on average 13% during the last 15 years, what was the total rate of return? Round your answer to the nearest whole number
