14% of $3900 = 0.14 x 3900 = $546\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "However, one must assume that the 14% is an annual rate, but the problem specifies only 90 days.
\n" ); document.write( "90 days is approximately 1/4 of a year.
\n" ); document.write( "1/4 of 546 = $136.50 interest due.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "After 90 days 3900 + 136.50 = $4,036.50 must be paid.
\n" ); document.write( "
\n" );
