Final answer:
The law of demand states that as the price of a good decreases, the consumer demand for it will increase, which is illustrated by sales flyers at grocery stores leading to increased purchases. The law of supply indicates that higher prices incentivize producers to supply more.
Step-by-step explanation:
The law of demand states that, ceteris paribus (all other factors being equal), as the price of a good or service decreases, consumer demand for it will increase, and vice versa. This inverse relationship can be represented graphically by a downward sloping demand curve in a price-quantity axis. Conversely, the law of supply posits that ceteris paribus, as the price of a good or service increases, producers will be willing to supply more of it to the market, reflecting a direct relationship that is shown as an upward sloping supply curve.
Sales flyers at grocery stores are an excellent example of demand in action. When grocery stores advertise sales, they effectively lower the price of certain goods. According to the law of demand, this should increase the quantity demanded as the goods become more affordable to consumers, influencing personal grocery shopping habits by encouraging the purchase of sale items over non-discounted goods.
