Expert Solution

Answer. Equilibrium Price = 20, Equilibrium Quantity = 6

Explanation

Total demand in the economy =Quantity demanded by ANNA + Quantity demanded by Beauty +Quantity demanded by Clive.

Using the given information the following Demand and Supply schedule and Curve are prepared.

(i) (ii) (iii) (iv) (v)= (ii)+(iii)+(iv) (vi)
Price Quantity Demanded by ANNA Quantity Demanded by Beauty Quantity Demanded by Clive Total Demand Total Supply
5 3 4 5 12 0
10 3 3 4 10 2
15 2 3 3 8 4
20 2 2 2 6 6
25 1 2 1 4 8
30 1 1 0 2 10
35 0 0 0 0 12

Equilibrium takes place where demand is equal to supply. From the above graph, we know that  equilibrium takes place at Price = 20. At this price, quantity demanded is equal to quantity supplied i.e. 6 kgs
