\n" ); document.write( "A loan of $48,000 is made at 8.75% interest, compounded annually.
\n" ); document.write( "After how many years will the amount due reach $ 153,000 or more?
\n" ); document.write( "Write the smallest possible whole number answer.
\n" ); document.write( "~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Use the formula for the annually compounded amount and write this inequality\r\n" );
document.write( "\r\n" );
document.write( "    \"48000%2A%281%2B0.0875%29%5Et\" >= 153000,\r\n" );
document.write( "\r\n" );
document.write( "where \"t\" is the time, in years\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Divide both sides by 48000\r\n" );
document.write( "\r\n" );
document.write( "    \"1.0875%5Et\" >= \"153000%2F48000\" = 3.1875.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Take logarithm of both sides\r\n" );
document.write( "\r\n" );
document.write( "    t*log(1.0875) >= log(3.1875) = 0.50345.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Find t\r\n" );
document.write( "\r\n" );
document.write( "    t >= \"0.50345%2Flog%28%281.0875%29%29\" = 13.82...\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Next, you should round this value of t to the closest greatest integer value,\r\n" );
document.write( "\r\n" );
document.write( "in order for the last compounding was performed.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, your answer is 14 years.\r\n" );
