\n" ); document.write( "\n" ); document.write( "        Tutor @MathTherapy mentioned very productive idea on use the backward method for this problem. \r
\n" ); document.write( "\n" ); document.write( "        In this my post I will show how effectively this idea works.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "So, let's stsart from the end.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Before Julie bought a pait of running choes, she had 17.75 + 29.45 = 47.20 dollars.\r\n" );
document.write( "\r\n" );
document.write( "This amount was the \"second half\" of her \"remaining\" money - so, the \"remaining\" money amount \r\n" );
document.write( "was 2*47.20 = 94.40 dollars .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, her paycheck was $ 94.40  PLUS  $30  PLUS  $30,  i.e.  94.40 + 10 + 30 = 134.40 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  The paycheck was $134.40.\r\n" );

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The backward method in this problem works  SO  EFFECTIVELY,
\n" ); document.write( "that the problem can be solved  MENTALLY  in couple of lines without using equations.\r
