Revenue = -o.1x^2 + 130x and the cost to produce x inkjet printers is given by Cost = 40x + 8000. Express the company's profit in terms of x.
\n" ); document.write( "-------------------------------------------------------
\n" ); document.write( "Profit = Revenue - Cost
\n" ); document.write( "Profit = -0.1x^2+130x - (40x+800)
\n" ); document.write( "= -0.1x^2+90x-800
\n" ); document.write( "----------------------------
\n" ); document.write( "Use this expression to find the profit from selling 400 inkjet printers.
\n" ); document.write( "P(400)=-0.1(400^2)+90(400)-800
\n" ); document.write( "P(400)= $19,200.00
