You are trying to get to Orlando, which is 800 miles away. You have 2,500 apples and a truck that can hold 1,000 apples at a time. You have unlimited gas, can take as many trips as you like, and can store apples anywhere along the road to pick up later. However, for every mile you drive, one apple falls out of the truck and is lost forever. What is the maximum number of apples you can deliver to Orlando? Solve this mentally, without paper or pencil.
