(28 points) The daily market for cups of coffee at Suzzalo Espresso is given by the following equations: Q = 60 - 10P and Q = 5P. Please answer the following questions about this market. a. (8 points) Identify the demand and supply equations from above. Solve for the equilibrium price and quantity in this market (in dollars and cups per day). Draw the supply and demand curves and equilibrium point on a graph. Be sure to label your axes.

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 sup. ply or demand is the equilibrium supply or equilibrium demand. Suppose the supply of a product is related to its price by the equation $$p=\frac{2}{3} q$$ where $p$ is in dollars and $q$ is supply in appropriate units. (Here, $q$ stands for quantity.) Furthermore, suppose demand and price for the same product are related by $$p=-\frac{1}{3} q+18$$ where $p$ is price and $q$ is demand. The system formed by these two equations has solution $(18,12),$ as seen in the graph. (GRAPH CANNOT COPY) Suppose the price and supply of the can opener are related by $p=\frac{3}{4} q,$ where $q$ represents the supply and $p$ the price. Find the supply at each price.
