\n" ); document.write( "
\r\n" );
document.write( "Let x = the amount, in pounds, of the $20.80 chocolate.\r\n" );
document.write( "\r\n" );
document.write( "Then the total amount of the mixture is  (x+10) pounds.\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( "\r\n" );
document.write( "    \"%2820.80%2Ax+%2B+3.00%2A10%29%2F%28x%2B10%29\" = 13.38.     (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "This equation says that the price of the mixture is $13.38 per pound.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "To solve equation (1), multiply both sides by (x+10)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    20.80*x + 3.00*10 = 13.38*(x+10),\r\n" );
document.write( "\r\n" );
document.write( "    20.80*x + 3.00*10 = 13.38*x + 13.38*10\r\n" );
document.write( "\r\n" );
document.write( "    20.80*x - 13.38*x = 13.38*10 - 3.00*10\r\n" );
document.write( "\r\n" );
document.write( "     7.42*x           = 103.80\r\n" );
document.write( "\r\n" );
document.write( "          x           = \"103.80%2F7.42\" = 13.989.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER: 13.989 pounds of the chocolate.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.    \"%2820.80%2A13.989%2B3%2A10%29%2F%2813.989%2B10%29\" = 13.38  dollars per pound of the mixture.    ! Correct !\r\n" );
