Jackie loves to climb trees. She climbed a 1000 foot tall tree. Then she climbed 2 trees that were half as tall as the first tree. She finished by climbing a tree that was 200 feet taller than her first tree. What was the average height of the trees that Jackie climbed? Give me reasons, before answering the question

Jackie climbed 2 trees that were 1 / 2 * 1000 feet = 500 feet tall each. Jackie climbed a final tree that was 1000 + 200 feet = 1200 feet. In total, the 4 trees Jackie climbed were 1000 feet + 500 feet + 500 feet + 1200 feet = 3200 feet. The average height tree that Jackie climbed was 3200 feet / 4 trees = 800 feet tall. So the final answer is 800.
