You want to build a 1200 square foot rectangular infinity pool. Three of the sides will have regular pool walls, and the fourth side will have the infinity pool wall. Regular pool walls cost $15 per foot (regardless of how deep the pool is), and the infinity pool wall costs $35 per foot (regardless of depth). How long should you make the infinity wall so that you minimize your costs?
