\r\n" );
document.write( "0.08x + 0.025(14000-x) = 757.\r\n" );

document.write( "Solve for x, which is the amount invested at 8%.\r\n" );

document.write( "x = \"%28757+-+0.025%2A14000%29%2F%280.08-0.025%29\" = (one click in my MS Excel) = 7400.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer.  7400 dollars were invested at 8%.  The rest,  14000-7400 = 6600 dollars were invested at 2.5%.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Check.  0.08*7400 + 0.025*6600 = 757 dollars.   ! Correct !\r\n" );
