To find:
The demand for the electric can opener at each price.
(a) $6
(b) $11
(c) $16
Suppose the demand and price for a certain model of electric can opener are related by,
Using the information supply and demand in many applications of economics, as the price of an item goes up, demand for the item goes down and supply of the item goes up. The price where supply and demand are equal is the equilibrium price, and the resulting supply or demand is the equilibrium supply or equilibrium demand.
Suppose the supply of a product is related to its price by the equation,
Where p is in dollars and q is supply in appropriate units. (Here, q stands for quality.) Furthermore, suppose demand and price for the same product are related by,
Where p is price and q is demand. The system formed by these two equations has solution (18, 12), as seen in the graph.
