7. Suppose a small town has 700 residents in it. There is a single public good, the town skating rink (y) and a single private good, food (x). Each individual may have a different level of food (x), but they all have the same level of the public good. 121 Everyone's utility function is the same: uj (x( y) = X1 - y The cost of the skating rink is $7 per square meter and the price of food is $1 per unit. What is the Pareto efficient size of a skating rink for this town? (8 points)
