$2.$ Future Value :

Using the Future Value of an Annuity Formula as shown in the Chapter $2$ lecture $($slide $23)$:

The actual results in the table on page $5$ of the article, based on a $$100$ monthly investment at an $11\%($Annual$)$ interest rate would be:

$$ $$8,024\mathrm{.}70$ total return in $5$ Years.

$$ $$45,885\mathrm{.}76$ total return in $15$ Years

$$ $$283,022\mathrm{.}78$ total return in $39$ Years

Change the interest rate to a more conservative $8\%$ annual rate. What would the results be from that change in total return dollars each year$/?$
