While playing a real-time strategy game, Juan created military units for battle: long swordsmen, spearmen, and crossbowmen. Long swordsmen require 75 units of food and 25 units of gold. Spearmen require 40 units of food and 30 units of wood. Crossbowmen require 30 units of wood and 40 units of gold. If Juan used 1475 units of gold, 1500 units of wood, and 4025 units of food to create the units, how many of each type of military unit did he create?
