#64. A snail creeps 9 ft up a wall during the daytime. After all the labor it does throughout the day, it stops to rest a while... but falls asleep!! The next morning it wakes up and discovers that it has slipped down 6 ft while sleeping.

If this happens every day, how many days will the snail take to reach the top of a wall 63 ft in height?
