Hi there,
\n" ); document.write( "Divide cost by rate
\n" ); document.write( "$150/0.25
\n" ); document.write( "= 600 ft^2
\n" ); document.write( "Divide total area by length
\n" ); document.write( "600/15
\n" ); document.write( "= 40
\n" ); document.write( "Width is 40 feet.
\n" ); document.write( "Hope this helps :-)
