1. Suppose we are interested in how the equilibrium price in the home aquarium industry changes with a one percent change in the income of consumers. Suppose further that we know the supply curve has a unit elasticity (1) and demand for home aquariums is elastic with an exact elasticity value of-1.2. Finally suppose that we have measured how many aquariums are sold and we know that a one percent increase in income results in three percent more aquariums sold. Find a number that will tell us the percentage change in aquarium equilibrium price associated with a one percent increase in income
