EXERCISE N. 1
The demand and supply curves for fixed gear bikes in Hipsterland are �� = 75 − 1.5� and �� =
1.5� − 30.
a. Find the equilibrium price;
b. Find the equilibrium quantity;
c. What are the consumer surplus, producer surplus, and total welfare at the market equilibrium?
qD = 75 – 1,5*p => p = 50 – 2/3*q
qS = 1,5*p – 30 => p = 20 + 2/3*q
75 – 1,5*p = 1,5*p – 30
3*p = 105
p* = 35
q* = 22,5
