Q: James builds a 20 story building. The first 10 stories are each 12 feet tall each. The remaining floors are each 3 feet taller. How tall is the building?
A: The first 10 floors are 10 * 12 = 120 feet. There are a remaining 20 - 10 = 10 stories. They are each 12 + 3 = 15 feet. So those stories are 15 * 10 = 150 feet. So the total height is 120 + 150 = 270 feet. The answer is 270.
