Suppose a stock had an initial price of $72 per share, paid a dividend of $1.20 per share during the year, and had an ending share price of $79.

Compute the percentage total return.

A stock had returns of 11 percent, 16 percent, 14 percent, 8 percent, 13 percent, and -1 percent over the last six years.
