A yogurt company estimates that the revenue from selling x containers of yogurt is 4.5x. Its cost, C, in dollars, for producing this # of containers of yogurt is C(s)=0.0001x^2+2x+3200. Determine the marginal profit from selling 4000 containers of yogurt.

Best ResponseYou've already chosen the best response.0My formula, to find the profit equation, is P(x)=R(x)C(x), which was 4.5x0.0001x^2+2x+3200.

Best ResponseYou've already chosen the best response.0The derivative was P'(x)=0.0002x+6.5 (according to my work, not sure). I then subbed in 4000 into that equation.

Best ResponseYou've already chosen the best response.1I think the error made is when u calculate marginal profits from total profits. Don't think it work that way. Marginal profits must be calculated from marginal cost and marginal revenue. So i went ahead to differentiate total cost, Marginal Cost, MC = 0.0002x+2 Substitute x= 4000, MC= 0.0002(4000)+2 = 2.8 Differentiating total revenue, marginal revenue, MR = 4.5 Marginal Profits = Marginal Revenue  Marginal Cost = 4.5  2.8 =1.7
