	Find the marginal revenue product if 20 employees produce x unit of a product per day where; 
x = 2n (3n + 1)^2
	and the demand function for a product is given by p=535/(x+5)^2 


The marginal revenue product (MRP) is calculated as the additional revenue generated by employing one more unit of input (in this case, labor). In your case, this is the additional revenue produced by the 21st employee, and it involves two components:

1. **Marginal product of labor (MPL)**: The additional output produced by hiring one more worker.
2. **Marginal revenue (MR)**: The additional revenue generated from selling the additional output.

### Step 1: Marginal Product of Labor (MPL)
The production function is given as:

\[
x = 2n (3n + 1)^2
\]

where \(x\) is the number of units produced and \(n\) is the number of workers. To find the marginal product of labor (MPL), we need to find how the output \(x\) changes with respect to the number of workers \(n\). This means finding the derivative of \(x\) with respect to \(n\).

\[
\frac{dx}{dn} = \text{MPL}
\]

Using the product rule for differentiation:

\[
x = 2n(3n+1)^2
\]

Differentiate:

\[
\frac{dx}{dn} = 2(3n+1)^2 + 2n \cdot 2(3n+1) \cdot 3
\]

Simplifying:

\[
\frac{dx}{dn} = 2(3n+1)^2 + 12n(3n+1)
\]

\[
= 2(3n+1)[(3n+1) + 6n] = 2(3n+1)(9n+1)
\]

So the marginal product of labor is:

\[
\frac{dx}{dn} = 2(3n+1)(9n+1)
\]

### Step 2: Marginal Revenue (MR)
The price \(p\) of the product is given by the demand function:

\[
p = \frac{535}{(x+5)^2}
\]

The total revenue \(R\) is:

\[
R = p \cdot x = \frac{535x}{(x+5)^2}
\]

Now, to find the marginal revenue, we take the derivative of revenue \(R\) with respect to \(x\):

\[
\frac{dR}{dx} = \text{MR}
\]

Using the quotient rule for differentiation:

\[
\frac{dR}{dx} = \frac{(x+5)^2 \cdot 535 - 535x \cdot 2(x+5)}{(x+5)^4}
\]

Simplify:

\[
\frac{dR}{dx} = \frac{535[(x+5)^2 - 2x(x+5)]}{(x+5)^4}
\]

Further simplification leads to:

\[
\frac{dR}{dx} = \frac{535[25 - x^2]}{(x+5)^4}
\]

So the marginal revenue is:

\[
\text{MR} = \frac{535(25 - x^2)}{(x+5)^4}
\]

### Step 3: Marginal Revenue Product (MRP)
The marginal revenue product is the product of the marginal product of labor (MPL) and the marginal revenue (MR):

\[
\text{MRP} = \text{MPL} \cdot \text{MR}
\]

Substituting the values we derived:

\[
\text{MRP} = \left[ 2(3n+1)(9n+1) \right] \cdot \left[ \frac{535(25 - x^2)}{(x+5)^4} \right]
\]

This gives the marginal revenue product, though a numerical result can be obtained by substituting specific values for \(n\) (like \(n = 20\)) and corresponding \(x\).

Would you like a detailed numerical solution, or do you have any specific clarifications so far?

1. How does marginal revenue change if demand elasticity changes?
2. What is the significance of diminishing marginal returns in this context?
3. How would changes in the demand function impact the marginal revenue product?
4. Can you interpret what happens when the marginal product of labor becomes negative?
5. What role does pricing strategy play in determining marginal revenue?

**Tip**: Understanding the relationship between marginal product and marginal revenue can help optimize labor and production costs effectively.
