Prove that…

If you have studied Economics before, you will be familiar with a linear downward sloping Demand curve. If you haven’t studied Economics before, its pretty straightforward. As price falls, quantity demanded of a product rises. Given this knowledge, and given that Average Revenue = Total Revenue divided by Quantity; can you prove that the Marginal Revenue (which is given by the formula: Change in Total Revenue / Change in Quantity) is twice as steep as the Demand Curve?
