Determine the cost of producing 200 air conditioners if the marginal cost (is per unit) is C'(x) = `x^2/200 + 4`

The marginal revenue (in thousands of Rupees) functions for a particular commodity is `5 + 3"e"^(- 003x)` where x denotes the number of units sold. Determine the total revenue from the sale of 100 units. (Given e^–3 = 0.05 approximately)

If the marginal revenue function for a commodity is MR = 9 – 4x². Find the demand function.

Given the marginal revenue function `4/(2x + 3)^2 - 1` show that the average revenue function is P = `4/(6x + 9) - 1`

A firm’s marginal revenue function is MR = `20"e"^((-x)/10) (1 - x/10)`. Find the corresponding demand function

The marginal cost of production of a firm is given by C'(x) = 5 + 0.13x, the marginal revenue is given by R'(x) = 18 and the fixed cost is ₹ 120. Find the profit function

If the marginal revenue function is R'(x) = 1500 – 4x – 3x². Find the revenue function and average revenue function

Find the revenue function and the demand function if the marginal revenue for x units is MR = 10 + 3x – x²
