In a particular geographical area, the demand function for each personifor a particular good is: qid= 100+ 0.2ii-9pwhere q is quantity demanded for person i, i is person i's income, and p is the commodity's price. note that p is constant across individuals, since all people face the same price. therefore there is no subscript. for the firms in this area the supply function for this good is: qj8= -50 +20pwhere in this equation q is the quantity supplied of the good by firm j. there are 5 firms and 100 consumers. total income of the consumers is $100,000. equilibrium occurs where100 σ qid= σqj8 i=1i. e. market demand equals market supply. find the equilibrium price.
