\r\n" );
document.write( "It follows directly from the condition that 44-18 = 26 gallons of fuel weight 2286-2117 = 169 pounds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Hence, 1 gallon of fuel weights  = 6.5 pounds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then 4 = 48-44 gallons weight 4*6.5 = 26 pounds,  \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "and the answer to the problem's question is 2286 + 26 = 2312 pounds.\r\n" );
