Final answer:
A customer's replenishment amount would be observed in a business or economic report or within a company's inventory system, changing in response to market forces such as shifts in demand and supply due to higher income and increased supply capacity.
Step-by-step explanation:
When considering where you would see a customer's replenishment amount changed, it is important to understand the context of the market and the forces that affect it.
For instance, if Figure 2.3 represents the market before a change, with a price of 150 rials and a quantity of 15,000 pounds, any change in the customer's replenishment amount would likely be observed in a business or economic report or within a company's inventory management system.
Changes in the market, such as employees receiving back pay and the main port reopening, would shift both the demand and supply curves, respectively.
An increase in consumer income, such as employees getting their back pay, would typically cause a shift in the demand curve to the right, indicating an increase in demand at each price level.
On the other hand, the main port reopening would likely cause a shift in the supply curve to the right as well, reflecting an increase in supply. These shifts would be reflected in the adjusted replenishment amounts as businesses respond to the new market equilibrium.
