John climbs up 3 flights of stairs. Each flight is 10 feet. He then climbs a rope that is half that height. Finally, he climbs a ladder that is 10 feet longer than the rope. How high up did he go? Give me reasons, before answering the question

He climbed 3 * 10 = 30 feet of stairs. He then climbed 30 / 2 = 15 feet of rope. Finally, he climbed a 15 + 10 = 25 foot ladder. So in total, he climbed 30 + 15 + 25 = 70 feet. So the final answer is 70.
