Question 1207431
.
Debbie plans to buy a house for cash instead of paying a mortgage. 
She is willing to set aside $12 OOO at the end of each year for 15 years. 
She invests the money in a high-risk mutual fund, which has traditionally earned 9.2% annually. 
Money decreases in value by 2.5% per annum. How much will Debbie have saved after 15 years?
~~~~~~~~~~~~~~~~~~~~~~


<pre>
First, calculate the future value of the ordinary annuity

    FV = {{{P*((1+r)^n-1)/r}}},


where  P is the annual payment at the end of each year (P = %12000);

       r is the rate of 9.2% (which is 0.092 decimal);

       n = 15 is the number of years.


So, FV = {{{12000*((1+0.092)^15-1)/0.092)}}} = 357917.24 dollars.


Then convert the todays' dollars into the future dollars at 2.5% inflation

     Debbie's cash in the future dollars = {{{357917.24/(1+0.025)^15}}} = 247129.53 future dollars.    <U>ANSWER</U>
