\n" ); document.write( "The demand equation for a certain type of printer is given by D=-200p+35,000. The supply equation is predicted to be: S=-p^2+400-20,000. Find the equilibrium price.

You can put this solution on YOUR website!
Equilibrium price is when the Demand is equal to the Supply.\r
\n" ); document.write( "\n" ); document.write( "\"D+=+S+\"
\n" ); document.write( "\"-200p%2B35000+=+-p%5E2%2B400-20000+\"
\n" ); document.write( "\"p%5E2+-+200p+%2B+54600+=+0+\"
\n" ); document.write( "This very similar to \"ax%5E2+%2B+bx+%2B+c+=+0+\"
\n" ); document.write( "Now solve with \"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
