A firm's total revenue function is given as TR = 10q - 10q². Find the firm's marginal revenue
To find the firm's marginal revenue, we need to take the derivative of the total revenue function with respect to quantity (q).
Given that TR = 10q - 10q², the derivative of this function with respect to q will give us the marginal revenue.
d(TR)/dq = d/dq (10q - 10q²) = 10 - 20q
Therefore, the firm's marginal revenue function is MR = 10 - 20q.
