Suppose that the revenue R, in dollars, from selling x clocks is R ( x )  = 30x. The cost C, in dollars, of selling x clocks is C ( x ) = 0.1x2 + 7x + 400. Show all your work and explain in sentences. Find the profit function, P ( x ) = R ( x ) – C ( x ). Find the profit if x =  30 clocks are sold. Interpret P (30).
