The revenue and cost function for a company that manufactures for washing were determine to be: r(x) = x(200-4x) and c(x) - 160 + 20x where x is the number of components in millions and r(x) and c(x) are in millions of dollars. How man's components must be sold in order for the to break, even points are when K(x) R(x) = c(x)) (Round answer to nearest million.) Find the profit equation. ( P(x) = R(x)- C(x)) Determine the maximum profit. How many components must be sold in order to achieve that maximum profile
