Final answer:
Changes in population can affect the price of goods through the interaction between supply, demand, and population growth.
Step-by-step explanation:
Changes in population can affect the price of goods. It depends on the interaction between population growth and changes in supply and demand. If the population increases and the supply of goods remains constant, there may be an increase in demand, which can lead to an increase in prices. On the other hand, if the population decreases or there is an increase in supply, the demand may decrease, which can result in lower prices.
