A. A reduction in the price of donuts will cause an increase in the demand for donuts. This is because the price of donuts is a determining factor in the quantity of donuts that consumers are willing to purchase. When the price of donuts decreases, consumers are more likely to buy them as they become more affordable.
This results in an increase in the demand for donuts.
B. An increase in consumer income will also cause an increase in the demand for donuts as they are considered a normal good. A normal good is a product whose demand increases as consumer income increases.
When consumers have more disposable income, they are more likely to spend it on goods and services that they enjoy, such as donuts. This increase in demand can be further attributed to the fact that consumers may view donuts as a luxury item, and therefore are more likely to purchase them when they have extra money to spend.
In summary, both a reduction in the price of donuts and an increase in consumer income can lead to an increase in the demand for donuts. Understanding how these factors impact the demand for specific goods is crucial for businesses that want to maximize their profits and stay competitive in the market.
