In this case, if the price of PlayStation 3 increases, consumers may be less willing to purchase it and instead opt for the cheaper alternative, which is the XBOX 360. As a result, the quantity demanded for XBOX 360 is expected to increase.

    When milk and chocolate chip cookies are complementary goods, it means that they are often consumed together. If the price of milk decreases, it becomes more affordable for consumers to purchase milk. This increase in affordability will likely lead to an increase in the quantity demanded for milk. As a result, consumers will also be more likely to purchase chocolate chip cookies to consume with the milk, leading to an increase in the quantity demanded for cookies as well.

    Demand is ________ when a change in price leads to a relatively larger change in the quantity demanded.  On the other hand, demand is __________ when a change in price leads to a relatively smaller change in the quantity demanded.

    • A.

      Increasing; decreasing

    • C.

      Elastic; inelastic

    • D.

      Inelastic; elastic

    Correct Answer
    C. Elastic; inelastic
    Explanation
    When a change in price leads to a relatively larger change in the quantity demanded, it indicates that the demand is elastic. This means that consumers are highly responsive to price changes, and a small increase or decrease in price can result in a significant increase or decrease in the quantity demanded. On the other hand, when a change in price leads to a relatively smaller change in the quantity demanded, it indicates that the demand is inelastic. This means that consumers are not very responsive to price changes, and even significant changes in price have minimal impact on the quantity demanded.

    Rate this question:

  • 10. 

    Increase in demand can occur due to which of the following?

    • A.

      Increase in price of the substitutes

    • B.

      Increase in income of the consumer

    • C.

      Decrease in price of the complementary good

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    An increase in demand can occur due to various factors, including an increase in the price of substitutes, an increase in the income of the consumer, and a decrease in the price of complementary goods. When the price of substitutes increases, consumers may switch to the original good, leading to an increase in demand. Similarly, an increase in consumer income allows them to afford more goods and services, resulting in higher demand. Additionally, a decrease in the price of complementary goods makes them more affordable, leading to an increase in demand for the original good. Therefore, all of these factors can contribute to an increase in demand.
