Larry and Barry want to pick apples out of the tree, but neither is tall enough to reach the apples.  Barry can reach apples that are 5 feet high.  Larry is 5 feet tall, but his shoulder height is 20% less than his full height.  If Barry stands on Larry's shoulders, how high can they reach? Let's think step by step and output the final answer after "####".

Larry's shoulder height is 20% less than 5 feet, or 0.2*5 =<<20*.01*5=1>>1 foot less than 5 feet.
One foot less than 5 feet is 5-1=<<5-1=4>>4 feet.
If Barry stands on Larry's shoulders, they can reach 4+5=<<4+5=9>>9 feet.
