If the demand function is given by the equation P = 10 – Qd, supply – P = 0.8Qs + 1. The equilibrium supply will be …

To find the equilibrium supply volume, you need to equate these supply and demand functions. Let’s find the inverse supply and demand functions and equate them:

Qd = 10 – P, Qs = (P – 1) / 0.8;

10 – P = P / 0.8 – 1.25;

2.25 * P = 11.25;

P = 5 days units;

To find the equilibrium supply volume, we put in any of the functions, since the demand volume will be equal to the supply volume:

Q = 10 – 5 = 5 units.

Answer: the equilibrium supply is 5 units.
