2. Why does a demand curve slope downward from left to right?

Explanation

A demand curve slopes downward from left to right because, as prices increase, consumers tend to purchase less of a good or service. This relationship reflects the basic economic principle of demand: when prices are high, the quantity demanded decreases, leading to a negative correlation between price and quantity demanded.

Submit

3. If the price of coffee rises, what happens to the quantity demanded?

Explanation

When the price of coffee rises, consumers tend to buy less of it because the higher price makes it less affordable or attractive compared to alternatives. This behavior aligns with the law of demand, which states that, all else being equal, an increase in price leads to a decrease in the quantity demanded.

Submit

4. The inverse relationship between price and quantity demanded is called the ____.

Explanation

The law of demand states that, all else being equal, as the price of a good decreases, the quantity demanded by consumers increases, and vice versa. This inverse relationship highlights how consumers tend to buy more of a product when it is cheaper and less when it is more expensive.

Submit

5. True or False: A downward sloping demand curve means consumers want less of a product when its price falls.

Explanation

A downward sloping demand curve indicates that as the price of a product decreases, consumers actually want more of it, not less. This reflects the basic principle of demand: lower prices typically lead to higher quantities demanded, demonstrating the inverse relationship between price and quantity demanded.

Submit

6. Which factor does NOT directly cause a shift in the demand curve?

Explanation

The price of the good itself affects the quantity demanded, leading to movement along the demand curve rather than a shift in the curve. In contrast, factors like consumer preferences, income levels, and the number of consumers can change overall demand, causing the entire curve to shift left or right.

Submit

7. When demand increases at every price level, the demand curve ____.

Explanation

When demand increases at every price level, consumers are willing to purchase more goods, leading to a higher quantity demanded. This change is represented graphically by a rightward shift of the demand curve, indicating that at each price, a greater quantity is sought compared to the previous demand situation.

Submit

8. Which scenario best illustrates the law of demand?

Explanation

This scenario exemplifies the law of demand, which states that as the price of a good decreases, the quantity demanded typically increases. By lowering jacket prices, the store attracts more customers, leading to higher sales, demonstrating the inverse relationship between price and quantity demanded.

Submit

9. The quantity demanded refers to the amount consumers want to buy at a ____ price.

Explanation

The quantity demanded indicates the precise amount of a good or service that consumers are willing to purchase at a particular price point. This relationship highlights how demand varies with price, emphasizing that demand is not just a general concept but is tied to specific pricing conditions.

Submit

10. True or False: An increase in consumer income always increases demand for all goods.

Explanation

An increase in consumer income does not always lead to higher demand for all goods. While it generally boosts demand for normal goods, it can decrease demand for inferior goods, which are typically purchased less as income rises. Thus, the relationship between income and demand varies depending on the type of good.

Submit

11. What is the relationship shown by a demand curve?

Explanation

A demand curve illustrates the relationship between the price of a good and the quantity demanded by consumers. As prices decrease, the quantity demanded typically increases, reflecting consumer behavior and preferences. This inverse relationship is fundamental in understanding market dynamics and consumer choices.

Submit

12. If smartphones become cheaper, consumers will likely buy ____.

Explanation

Additionally, lower prices can encourage existing users to upgrade or replace their phones more frequently.

Submit

13. A change in consumer preferences for a product causes the demand curve to ____.
