The total cost C (x) and the total revenue R (X) associated with the production and sale of x units of an item are given by `C(x) = 0.1 x^2 + 30 x + 1000` and `R(x) = 0.2x^2 + 36x - 100` find the marginal cost and the marginal revenue when x = 20.

The total cost C(x) and the total revenue R(x) associated with the production and sale of x units of an item are given by C(x)=0.1x^2+30x+1000 and R(X)=0.2x^2+36x-100 . Find the marginal cost and mardinal revenue when x=20.

Find the marginal cost and the marginal revenue when x = 10 , the total cost C(x) and the total revenue R (x) in Rupees, associated with production and sale of x units of an item are given by C (x) = 0.003 x^3 + 0.02 x^2 + 20 x + 1200 R (x) = 0.1 x^2 + 25 x - 100 .

The total cost C(x) in Rupees associated with the production of x units of an item is given by C(x) = 0.007x^3 + 0.003x^2 + 15x + 4000 Find the marginal cost when 17 units are produced.

The total cost C(x) in Rupees, associated with the production of x units of an item is given by C(x) = 0.005 x^3 - 0.02 x^2 + 30x + 5000 Find the marginal cost when 3 units are produced, where by marginal cost we mean the instantaneous rate of change of total cost at any level of output.

The total cost C(x) associated with product of 'x' units of an item is given by: C(x) =0.005 x^3-0.02x^2 + 30 x + 500 . Find the marginal cost when 3 units are produced.

The total revenue received from the sale of 'x' units of a product is given by R (x) = 3x^2 + 36x + 5 . Find the marginal revenue when x = 5.
