Question

if the supply and demand functions for a commodity are given by p-q=10 and q(2p-10)=2100, what is the equilibrium price and what is the corresponding number of units supplies and demanded

Answer 1

Answer:

If p - q = 10, then p = 10 + q.  Replace the other p with this:

q(2(10 + q) - 10) = 3600

q(20 + 2q - 10) = 3600

q(10 + 2q) = 360
