The scenarios that represent business incentives created to increase the demand of consumers in the marketplace are:
B) A pizzeria offers a promotion of buy one, get one half price.
D) A tax break is offered to homes that install energy-efficient appliances.
In scenario B, the pizzeria is offering a promotional discount (buy one, get one half price), which is a common business strategy to attract more customers and increase demand.
In scenario D, offering a tax break for homes that install energy-efficient appliances creates an incentive for consumers to purchase such appliances, thereby increasing demand for those specific products.
These incentives aim to influence consumer behavior and stimulate demand for the respective goods or services.
