Jabari's HookNLadder is the only company selling fire engines in the fictional country of Alexandrina. Jabari initially produced eight trucks, but then decided to increase production to nine 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 $80,000 to $60,000 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 eight 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 eight engines by selling at $60,000 rather than $80,000. Then use the green rectangle (triangle symbols) to shade the area representing the revenue gained from selling an additional engine at $60,000.     Jabari (should/should not)   increase production from 8 to 9 fire engines because the (price effect/output effect)   dominates in this scenario.
