Answer: The answer has been attached.
Explanation:
The marginal revenue is the increase in revenue which is due to the extras sale of an additional unit of output. From the question, we are informed that the inverse demand function is p=300 −3Q. It should be noted that to calculate marginal revenue, the total revenue has to be known first.
Total revenue is the product of the price and quantity. This will be:
TR= (300 - 3q) × q
TR = 300q - 3q²
After calculating the total revenue, then the marginal revenue can be gotten.
The marginal revenue function will be 300 - 6q.
