You have just received word that your original investment of \$650 has increased in value by 17%. What is the value of your investment today?

I have no idea how to work this problem. Someone show me how to please

Hi Elizabeth,

In order to solve this problem we would first need to find out what 17% of the original value is in dollars. This can be found by:

• 650 x (17/100) = 650 x 0.17 = \$110.5

What this is telling us, is that the original investment has increased by \$110.5. Therefore our final answer will be:

• 650 + 110.5 = \$760.5

Hope this helps!

Thank you so much!

You're very welcome!

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
