When I try to give an answer it tells me wrong and then tells me to substitute 3.30 with the cost and solve for the length.

\r\n" );
document.write( "For the last part:\r\n" );
document.write( "If the report has x pages,\r\n" );
document.write( "the cost is 1.8 + 0.05*x (fixed binding cost + variable cost per page)\r\n" );
document.write( "This is given to be 3.3\r\n" );
document.write( "\r\n" );
document.write( "So 3.3 = 1.8 + 0.05*x\r\n" );
document.write( "0.05*x = 1.5\r\n" );
document.write( "x = 1.5/0.05 = 30\r\n" );
document.write( "Report has 30 pages :)\r\n" );
document.write( "
