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).
TR = 10q - 10q²
To find the marginal revenue (MR), we need to find the derivative of TR with respect to q:
MR = d(TR)/dq
MR = d(10q - 10q²)/dq
MR = 10 - 20q
Therefore, the firm's marginal revenue function is MR = 10 - 20q.
