For your introduction to this type of problem you should solve it this way so you understand how it works:

Since you started with $650 and it went up by 17%, you can calculate what 17% of $650 is, then add that to the starting amount.

17% is the same as 0.17, so 17% of $650 is:

$650 * 0.17 = $110.50

This is the amount of the gain. Just add it to $650:

Amount today = $650 + $110.50 = $760.50

-----------------

After you get a little practice with doing it that way, you can speed it up a bit.

As of today you still have 100% of the original investment, plus 17% more.

You can add 100% + 17% to get 117%. Multiply that times the original investment.

117% = 1.17

$650 * 1.17 = $760.50
