3. The components of marginal revenue
Jabar's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Jabari initially produced five trucks, but then
decided to increase production to six trucks. The following graph gives the demand curve faced by Jabari's HookNLadder. As the graph shows, in order
to sell the additional fire truck, Jabari must lower the price from $160,000 to $120,000 per truck. Notice that Jabari gains revenue from the sale of the
additional engine, but at the same time, he loses revenue from the initial five 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 five engines by selling at $120,000 rather
than $160,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine
at $120,000.
