Fraction invested at 8%:  
\n" );
document.write( "Let amount be A
\n" );
document.write( "Then we get: 
\n" );
document.write( "3(.12A) + 5(.05A) + .32A = 41,850 ------- Multiplying by LCD, 15
\n" );
document.write( ".36A + .25A + .32A = 41,850
\n" );
document.write( ".93A = 41,850
\n" );
document.write( "A, or amount inherited =  \n" );
document.write( "
