The weekly profit(in dollars) of a company making and selling x virtual pets each week is given by P(x) = -x^2 + 980x - 3000.
\n" ); document.write( " What is the maximum profit, and how many virtual pets should be made and sold each week to maximize profit?
\n" ); document.write( ":
\n" ); document.write( "-x^2 + 980x - 3000 is quadratic equation, the max value is on the axis of symmetry.
\n" ); document.write( " Use the formula x = -b/(2a), where a=-1; b=980
\n" ); document.write( "x = $\"%28-980%29%2F%282%2A-1%29\"$
\n" ); document.write( "x = +490 items sold for max profit
\n" ); document.write( ":
\n" ); document.write( "Find the actual profit at his value
\n" ); document.write( "P(x) = -490^2 + 980(490) - 3000
\n" ); document.write( "P(x) = -240100 + 480200 - 3000
\n" ); document.write( "P(x) = $237,100 profit \n" ); document.write( "

\n" );
