1) according to the table, what has the investor done with money earned through interest? 2) from looking at the table, explain the concept of compound interest. 3) according to the table, if the interest rate on this account were 10 percent, how much money would you have in the account at the end of the first year? 4) according to the table, if you added $50 to this account every year, what effect would it have on the interest rate that you earned? according to the table, the investment has doubled in worth by the start of which year? table: start of year principal amount interest earned at 5% principal at end of year - $100 $5 $105 1 $105 $5.25 $110 2 $110.25 $5.51 $115.76 3 $115.76 $5.79 $121.55 4 $121.55 $6.08 $127.63 and it just follows that pattern

Based on the given figures in the table, the following are true:

The investor according to the table, reinvested the interest they earned back into the account so that they would make interest on that additional interest as well. This is how the concept of compound interest works.

If the rate was 10%, the money in the account would have been:

= 100 x ( 1 + 10%)

= $110

The rate is 5% and this will not change regardless of the $50 added. The interest earned will however increase.

The initial investment was $100 and this became $207.90 at the end of the 14th year. This means that the amount doubled to $200 sometime during the 14th year.

In conclusion, compound interest grants interest on interest.
