A snail creeps 6 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 3 ft while sleeping.
If this happens every day, how many days will the snail take to reach the top of a wall 18 ft in height?
