positive, that is, Coke and Pepsi are substitutes.
By itself, an increase in the number of suppliers in a market results in a
rightward shift in the supply curve.

shows combinations of two activities that are attainable with given resources.
Each point on the demand curve reflects
the highest price consumers are willing and able to pay for that particular unit of a good.
The more substitutes available for a product,
the larger is its the price elasticity of demand.
Each point on a supply curve represents
