2. Graph and numerically solve for the equilibrium price and quantity by setting demand and supply equal to one another: Demand: q = 100-5p Supply: q = 15p 3. Graph and numerically solve for the equilibrium price and quantity by setting demand and supply equal to one another: Demand: q = 10-p Supply: q = 2 + 3p 4. Calculate and interpret (inelastic, elastic, unit elastic) elasticities of demand: a. Original Price is $10 and quantity demanded is 100 New price is $12 and quantity demanded is 75 b. Original Price is $100 and quantity demanded is 200 New price is $80 and quantity demanded is 220
