Alfonso wants to know what the cost of living would be in four different cities. He looks at circular ads from each of the cities and finds the prices of goods that he would normally buy during a typical trip to the grocery store each week. He adds up what he would pay for each grocery trip in the different cities and calls the sum “Price of Grocery Basket.” He compares theses costs to what he would earn in each city.
Compute Alfonso’s real wage in terms of how many baskets of groceries his wage could purchase and complete the “Real Wage” column with this information.
Instructions: Round your answers to whole numbers.

What is one difference between a firm in a perfectly competitive industry and a firm in a monopolistically competitive industry?
A monopolistically competitive firm does not have the exact same product as other firms.
A monopolistically competitive firm does not choose a level of output where marginal cost is equal to marginal revenue.
