Coach Stauder is going on vacation. He first goes to Colorado in which the highest mountain (Mount Elbert) he can hike is approximately 14,500 feet above sea level. He then goes to the lowest point in the US, Death Valley, which is 282 feet below sea level. On the trip he spends $500, but doubles what he spent for the trip by playing the slots in Vegas.
