document.write( "Question 1169702: Eugene began to save for his retirement at age 29, and for 11 years he put $ 500 per month into an ordinary annuity at an annual interest rate of 9% compounded monthly. After the 11 years, Eugene was unable to make the monthly contribution of $ 500, so he moved the money from the annuity into another account that earned 12% interest compounded monthly.

\r\n" );
document.write( "Solve it in two steps.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "First, determine future value FV1 of the account after first 11 years.  \r\n" );
document.write( "Use the standard formula for the ordinary annuity\r\n" );
document.write( "\r\n" );
document.write( "    FV1 = \"500%2A%28%281%2B0.09%2F12%29%5E%2811%2A12%29-1%29%2F%28%280.09%2F12%29%29%29\" = 112,087.42 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, find future value FV2 of this amount, $112,087.42, in the another account that earned 12%\r\n" );

document.write( "\r\n" );
document.write( "    FV2 = \"112087.42%2A%281%2B0.12%2F12%29%5E%2812%2A25%29\" = \"112087.42%2A1.01%5E300\" = $2,218,038.13.\r\n" );
