Answer:
When the price of a necessity increases, demand is likely to be constant because consumers need that product to survive. However, when the price of a luxury good increases, consumers may not buy it because the good is not crucial to survival. Thus, the demand would be decreasing.
Step-by-step explanation:
Changes in prices do not affect the demand for necessary goods in price. Consumers need products to survive. Luxury goods are not a necessity for life. When the price goes up, the demand goes down.
