1.	The total revenue received from the sale of x units of a product is given by R(x) = 13x2 + 26x + 15 Find marginal cost when x = 15
Answer» Given, R(x) = 13x² + 26x + 15 Marginal cost MR(x) = d/dx{R(x)} = d/dx(13x² + 26X + 15) = 26x + 26 Putting x = 15 Then MR(x) = 26 × 15 + 26 = 390 + 26 MR (7) =416 Hence, Marginal cost = Rs. 416

The total revenue received from the sale of x units of a product is given by R(x) = 13x2 + 26x + 15 Find marginal cost when x = 15

Answer»

Given,
R(x) = 13x² + 26x + 15

Marginal cost MR(x) = d/dx{R(x)}

= d/dx(13x² + 26X + 15)

= 26x + 26

Putting x = 15

Then MR(x) = 26 × 15 + 26

= 390 + 26

MR (7) =416

Hence,

Marginal cost = Rs. 416
