Final answer:
Influences such as input costs, supplier numbers, taxes, and technology affect the supply side of the market. They shape production costs and firms' willingness to supply goods at certain prices.
Step-by-step explanation:
The price of inputs, number of suppliers, taxes, and technology are all influences on supply. Factors such as changes in the cost of inputs, natural disasters, new technologies, and government decisions can affect the cost of production, altering how much firms are willing to supply at any given price. Businesses often strive to produce at a lower cost to achieve higher profits, but if the cost of a key input rises, the firm must decide whether to pass these costs onto consumers or absorb them. Conversely, if production becomes cheaper due to technological advancements, this could either increase the firm's profits or lead to lower prices for consumers depending on the market competition and the price elasticity of demand.
