The demand and supply functions for two interdependent commodities are given by QD, = 100 – 2P, + P, On, = 5 + 2P, – 3P, Qs, = -10 + P, Os, = -5 + 6P, where Qp, Qs and P, denote the quantity demanded, quantity supplied and price of good i, respectively. Determine the equilibrium price and quantity for this two-commodity model.

Consider the web model with the supply and demand equations given by  Find the intertemporal equilibrium price, and determine the equilibrium rate and its stability.

a. find the equilibrium point (both the p and q) b. find new equilibrium point with a $0.40 tax imposed on the suplier (both p and q)

Find the point of equilibrium for the following supply and demand equations where ? is number of units and ? is the price per unit. Demand: ?=74−0.000030?=74−0.000030q Supply: ?=43+0.000280?=43+0.000280q Number of units for equilibrium =  Price per unit at equilibrium =
