a) equilibrium at Qd = Qs

65 - 10P = -35 + 15P

100 = 25P

P = 4

Q = 65 – (10 "\\times" 4) = 25

equilibrium price is $4 and quantity is 25

b)

i) if P = 6

Qd = 65 – (10 "\\times" 6) = 6

Qs = -35 + (15 "\\times" 6) = 55

The market is in not equilibrium and market is having surplus due to higher price. quantity supplied is exceed quantity demanded.

ii) if P = 2

Qd = 65 - (10 "\\times" 2) = 45

Qs = -35 + (15 "\\times" 2) = -5

The market demand is not equilibrium and since price is low than equilibrium and there is a shortage in market

c)
