Answer:
Equilibrium price, p = 2.5
Equilibrium Quantity, Q = 22.5
Explanation:
The equation is:
Qd = 30 - 3p
Qs = 10 + 5p
At equilibrium, Quantity demanded equals quantity supplied
Equate Qd = Qs to find equilibrium price
30 - 3p = 10 + 5p
30 - 10 = 5p + 3p
20 = 8p
p = 20/8
P = 2.5
Substitute equilibrium price into Qd and Qs equation to find equilibrium Quantity
Qd = 30 - 3p
= 30 - 3(2.5)
= 30 - 7.5
= 22.5
Qs = 10 + 5p
= 10 + 5(2.5)
= 10 + 12.5
= 22.5
Therefore,
Equilibrium price, p = 2.5
Equilibrium Quantity, Q = 22.5
