In equilibrium
Demand= supply
42-Q=2Q
42=Q+2Q
42=3Q
Q=42\3
Q=14
Substituting Q into supply equation
P=2*14
=28
a. At P=35
35=2Qs
Qs=35\2
Qs=17.5
Qd=42-35
Qd=7
It means only 7 units are traded.
b.
The buyer will be dissatisfied because price is above equilibrium and there is surplus.
C.
When P=14
Qs=P\2
=14\2
=7 units
Qd=42-14
Qd=28
It means only 7 units are traded.
D.
Since sellers are getting below equilibrium price, so seller will be dissatisfied.
E. Equilibrium quantity is 14 units.
F.
Equilibrium price=28
G.
TR=P*Q
=14*28
=392
