You can put this solution on YOUR website!
Let p = the original price
\n" ); document.write( "Let n = the number sold
\n" ); document.write( "Since the amount raised is $240, we have n*p = 240
\n" ); document.write( "If they had lowered the price by $2, they would have needed to sell 20 more to make $240.
\n" ); document.write( "The equation for this is (n+20)(p-2) = 240
\n" ); document.write( "Solve for p in the 1st equation and substitute in the 2nd:
\n" ); document.write( "(n+20)(240/n-2) = 240
\n" ); document.write( "If you perform the multiplication and simplify, your are left with
\n" ); document.write( "n^2 + 20n - 2400 = 0
\n" ); document.write( "Factor:
\n" ); document.write( "(n+60)(n-40) = 0
\n" ); document.write( "Take the positive solution, n = 40
\n" ); document.write( "So they sold 40 pocket protectors at a cost of $6 each
\n" ); document.write( "
\n" );
