Brain Teaser: Sam, Scott, and Skip are roommates. Skip got up early one morning and went to the bakery to get some doughnut holes. When he returned, both of his roommates were still asleep so Skip went ahead and ate a third of the doughnut holes and went to work. When Sam woke up, he saw the doughnut holes on the counter so he ate a third of what was left and headed to school. A couple hours later, Scott finally woke up to find the doughnut holes. He ate a third of what was left. As Scott finished his last doughnut hole, Sam and Skip returned to find that there were still 16 doughnut holes still on the counter. How many doughnut holes did Skip initially buy?
