A certain manufacturer has determined that the weekly demand and supply
functions for their product are given by the equations:
supply:
p=-2x² +80
demand: p = 15x+30
where z represents the quantity demanded in units of a thousand and p is the unit
price in dollars. Find the market equilibrium (equilibrium price and equilibrium
quantity).
Assume that demand for a commodity is represented by the equation P = 10 − .2Qd and supply by the equation P = 2 + .2Qs, where Qd and Qs are quantity demanded and quantity supplied, respectively, and P is price. Using the equilibrium condition Qs = Qd, solve the equations to determine equilibrium price. Now determine equilibrium quantity.
