The maximum is where x=-b/2a=-1250/-70=$17.86 and will make $4660.71 in profit. That is the price at which profit is maximized.
\n" ); document.write( "The roots represent where the profit is 0 or breakeven.
\n" ); document.write( "Set y=3000 and solve for -35x^2+1250x-9500=0
\n" ); document.write( "or 35x^2-1250x+9500=0; 7x^2-250x+1900=0
\n" ); document.write( "x=(1/14)* (250+/- sqrt (9300))
\n" ); document.write( "=(1/14)(250+/- 96.44)
\n" ); document.write( "=$24.74 or $10.98
\n" ); document.write( "between ($10.98 and $24.74)\r
