Astock was purchased at $15.75 per share and sold at $19.25 per share what was the profit per share

The profit per share can be solved by subtracting the amount that is initially paid to buy or purchased the share from the final amount when it was finally sold. From the given values above, the profit per share will be,
             profit per share = $19.25 - $15.75
                                         = $3.5
Thus, each share will gain $3.5.
