You can put this solution on YOUR website!
When you can supply the demand, you have reached an equil amount.
\n" ); document.write( "D = S
\n" ); document.write( "-5p + 40 = -p^2 + 30p - 8
\n" ); document.write( "p^2 - 35p + 48 = 0
\n" ); document.write( "Solve as you would like from here:
\n" ); document.write( "p^2 - 35p = -48
\n" ); document.write( "(p - 17.5)^2 = 258.25
\n" ); document.write( "p = 17.5 +- sqrt(258.25)
\n" ); document.write( "when p is about 33.6 or 1.4
\n" ); document.write( "
\n" );
