The local zoo has hired you to assist them in setting admission prices. the zoo's managers recognize that there are two distinct demand curves for zoo admission. one demand curve applies to those ages 12 to 64, while the other is for children and senior citizens. the two demand and marginal revenue curves are: pa = 9.6 - 0.08qa mra = 9.6 - 0.16qa pcs = 4 - 0.05qcs mrcs = 4 - 0.10qcs where pa = adult price, pcs = children's/senior citizen's price, qa = daily quantity of adults, and qcs = daily quantity of children and senior citizens. crowding is not a problem at the zoo, so that the managers consider marginal cost to be zero. hint: whenever inverse demand is p=a-bq, marginal revenue is mr=a-2bq a. to start, what is the total revenue that would be collected if the zoo decides not to price discriminate?
