You want to build a 1100 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 $16 per foot (regardless of how deep the pool is), and the infinity pool wall costs $40 per foot (regardless of depth). How long should you make the infinity wall so that you minimize your costs?
