You can put this solution on YOUR website!
since 400 - 4p is the denominator, it will be undefined when 400 - 4p = 0.
\n" ); document.write( "that will occur when p = 100% because 400 - 4*100 = 400 - 400 = 0.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you cannot divide by 0, so the answer, when the denominator is equal to 0, is undefined.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your other answers look ok.
