A manufacturer of radios estimates that his daily cost of producing x radios is given by the equation C=350+5x. The equation R=25x represents the revenue in dollars from selling x radios.
*Profit function,P(x)=R(x)C(x),P(x)=20x350
*How many radios should the manufacturer produce and sell to have a daily profit of $500?
