Question

The total revenue in Rupees received from the sale of x units of a product is given by
R(x) = 13x² + 26x + 15.
Find the marginal revenue when x = 7.

Solution

R(x) = 13x² + 26x + 15 $rightwards double arrow space space space space space straight R space equals space 13 straight x squared plus 26 straight x plus 15$
Marginal revenue = $dR over dx space equals space 26 straight x plus 26$
When x = 7, marginal revenue = 26(7) + 26 = 182 + 26 = Rs. 208
