Assume a demand equation:
Qd= 9 - 0.1p - pc +0.01ps + 0.0001Y

and Supply equation:
Qs= 0.1p - 0.02pi +0.01N +0.01T - 0.1w

where
p= Price of the good
pc= price of the complement= $3
ps= price of substitute = $200
Y= Conusmer income= $20,000
Q= Quantity in thousands of units
pi= price of an input = $450
N= number of firms= 700
T= index of technology=300
w= wage rate= $10

Required:
If the price is $60, there will be an excess supply excess demand of nothing thousand units.
