3. The components of marginal revenue Mo's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Mo initially produced four trucks, but then decided to increase production to five trucks. The following graph gives the demand curve faced by Mo's HookNLadder. As the graph shows, in order to sell the additional fire truck, Mo must lower the price from $105,000 to $90,000 per truck. Notice that Mo gains revenue from the sale of the additional engine, but at the same time, he loses revenue from the initial four engines because they are all sold at the lower price. Use the purple rectangle (diamond symbols) to shade the area representing the revenue lost from the initial four engines by selling at $90,000 rather than $105,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $90,000. PRICE (Thousands of dollars per fire engine) Mo Revenue Lost 120 Demand 105 Revenue…
