Answer:
Candy is old, and handicapped-he only has one hand. Candy offers to give his "life savings" of $200 to help George and Lennie buy the land.
Explanation: Like all of us, Candy had dreams and aspirations. Now he is old, handicapped and his only companion, the dog he raised from a puppy has been shot by Carlson to put the dog out of his misery as he was also old and suffering. The idea of having land, and being a landowner will, in Candy's mind allow him to live out the rest of his life with a certain dignity and a sense of achievement.
