Step-by-step explanation:

When new providers enter a competitive market, parameters such as equilibrium price, supply and demand tend to change. The higher the number of sellers, the higher the production tends to be for each price level. The same is true if production costs go down, as this is an incentive for each salesperson to produce and deliver more so as to maximize their revenue.
