Suppose that the revenue function for a certain product is given by R(x) = 17(2x + 1)−1 + 34x − 17 where x is in thousands of units and R is in thousands of dollars. (a) Find the marginal revenue (in thousands of dollars) when 2000 units are sold. $ 34 Incorrect: Your answer is incorrect. thousand (b) How does the revenue change when 2000 units are sold?

Answer:

Step-by-step explanation:

Given that:

R(x) = [tex]\frac{17}{2x+1}[/tex] + 34x − 17

As we know that derivative of revenue function is marginal revenue function .

We will use following rules of derivative

=> dR/ dx = [tex]\frac{-17*2}{(2x+1)^{2} } + 34[/tex]

=> R' (x) =   [tex]\frac{-34}{(2x+1)^{2} } + 34[/tex]

=> R '(2000) =  [tex]\frac{-34}{(2*2000+1)^{2} } + 34[/tex] = 34

The revenue when 2000 units are sold is:

R(2000) = [tex]\frac{17}{2*2000+1}[/tex] + 34*2000 − 17 = $69,783

The marginal revenue be "34" and revenue change be "$69,783".

Marginal revenue:

The increase throughout income caused by the acquisition of one more unit of production, is a Marginal revenue. Although marginal income can stay unchanged at a predetermined interval, it's indeed subject to the regulations of decreasing returns as well as will ultimately slow as outcome level grows.

According to the question,

Revenue function,

R(x) = [tex]\frac{17}{2x+1}[/tex] + 34x - 17

Units sold = 2000

(a) The marginal revenue be:

→ [tex]\frac{dR}{dx}[/tex] = [tex]-\frac{17\times 2}{(2x+1)^2}[/tex] + 34

R'(x) = [tex]- \frac{34}{(2x+1)^2}[/tex] + 34

By substituting "x = 2000",

R'(2000) = [tex]- \frac{34}{(2\times 2000+1)^2}[/tex] + 34

              = 34

(b) The revenue change be:

→ R(2000) = [tex]\frac{17}{2\times 2000+1}[/tex] + 34 × 2000 - 17

                 = 69,783 ($)

Thus the above response is appropriate.
