\n" ); document.write( "~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "Let x be the lower price.\r\n" );
document.write( "\r\n" );
document.write( "Then the higher price was (x+0.10).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the condition, you have this equation\r\n" );
document.write( "\r\n" );
document.write( "    \"3.60%2Fx\" - \"3.60%2F%28x%2B0.10%29\" = 3\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To simplify, divide both sides by 3\r\n" );
document.write( "\r\n" );
document.write( "    \"1.20%2Fx\" - \"1.20%2F%28x%2B0.10%29\" = 1.      (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now you can guess the answer MENTALLY:  x = 0.30.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  \"1.20%2F0.30\" - \"1.20%2F0.40\" = 4 - 3 = 1.    ! Correct !\r\n" );
