The total revenue in Rupees received from the sale of x units of a product is given by `R(x)=3x^2+36 x+5`. Find the marginal revenue, when `x = 5`, where by marginal revenue we mean the rate of change of total revenue with respect to the nu

Explanation

Given, `R(x)= 3x^2+36x+5`

marginal revenue` = {dR}/{dx}=6x + 36`

Thus at x= 15, Marginal revenue `=6(15)+36= 126`
