In a crowded city far away, the civic authorities decided that rents were too high. The long-run supply function of two-room rental apartments was given by q = 15 + 3p and the long-run demand function was given by q = 237 - 3p, where p is the rental rate in crowns per week. The authorities made it illegal to rent an apartment for more than 30 crowns per week. To avoid a housing shortage, the authorities agreed to pay landlords enough of a subsidy to make supply equal to demand. How much would the weekly subsidy per apartment have to be to eliminate excess demand at the ceiling price?
