A company that manufactures flash drives knows that the number of drives x it can sell each week is related to the price p, in dollars, of each drive by the equation x=1200-100p
\n" ); document.write( "Find the price p that will bring in the maximum revenue.
\n" ); document.write( ":
\n" ); document.write( "R = p * x
\n" ); document.write( "replace x with 1200-100p
\n" ); document.write( "R(p) = p(1200-100p)
\n" ); document.write( "R(p) = 1200p - 100p^2
\n" ); document.write( "or
\n" ); document.write( "R(p) = -100p^2 + 1200p
\n" ); document.write( "using the vertex formula: p = -b/(2a) where a = -100, b = 1200
\n" ); document.write( "p = \"%28-1200%29%2F%282%28-100%29%29\"
\n" ); document.write( "p = $6 is the price that will give max revenue
\n" ); document.write( " \n" ); document.write( "
\n" );
