.


It is ELEMENTARY . . . 


<pre>
<U>STEP 1</U>.  Determine future value after first 5 years.


We have classic Ordinary Annuity saving plan  (see the lessons

in this site).


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


where  FV is the future value of the account;  P is the monthly payment (deposit); r is the monthly percentage yield presented as a decimal; 
n is the number of deposits (= the number of years multiplied by 12, in this case).


Under the given conditions, P = 140;  r = 0.09/12;  n = 12*5 = 60.  So, according to the formula (1), you get at the end of the 5-th year


    FV = {{{140*(((1+0.09/12)^60-1)/((0.09/12)))}}} = = $10,559.38.



<U>STEP 2</U>.  without making additional deposits, in the account for another 28 years.


    FV = {{{10559.38*(1+0.09/12)^(12*28)}}} = 130,010 dollars.


<U>ANSWER</U>.  At the end, the account will be $130,010.

Solved.
