Get a Grip!

 

 

At the construction site two apprentices are trying to hoist a bucket of cement on a pulley up to Mary, the master mason, at the top of a scaffolding 20' up.  The two apprentices are having a bit of trouble keeping a grip on the rope of the pulley.  Each time the two of them pull on the rope, the bucket goes up 5', but they have trouble holding it tight and the bucket always slips down one foot after each pull.  How many pulls will it take for the bucket to reach Mary?

 

 

 

 

 

Good Luck!!!!!
