Final answer:
Inputs like unit price, unit of issue, and quantity unit pack affect supply and demand within a business, which can be graphically represented with specific numbers on the price and quantity axis. Changes in consumer preferences, as demonstrated with news consumption shifting from traditional to digital sources, signify a change in demand.
Step-by-step explanation:
The input that changes the unit price, unit of issue, and quantity unit pack typically refers to factors affecting the supply chain and inventory management within a business context. When there is a change in these inputs, it impacts the cost of goods sold and can thereby affect both supply and demand. For instance, as seen in the provided example, a shift in consumer preference from traditional news sources to digital sources has led to a change in demand for the former. This change in demand can be represented on a graph with the use of specific numbers on the price and quantity axis. Further, understanding how these changes affect elasticity is crucial for businesses, as represented in Table 5.1 Elastic, Inelastic, and Unitary: Three Cases of Elasticity, which showcases the relationships between the percentage change in quantity demanded and the percentage change in price.
