#### Explanation:

Depending on whether you use simple or compound interest. I would think the stock would be worth:

$750xx1.25=$937.50 at the end of one year,

$937.50xx1.25=$1171.88 at the end of two years, and

$1171.88xx1.25=$1464.84 at the end of three years.

Or, if you want to compute it in one shot,

$750xx1.25^3=$1464.84.
