There are only two individuals that make up the market demand for this market. Person 1 is willing to pay a price P = 200 - 50 q1 for each quantity q1 that person 1 consumes. The willingness to pay for person 2 is P = 200 - 100 q2 .
a) Give a formula for the market demand.
b) If the market supply is Q=(400+8P)/200, what is the equilibrium price and quantity?
