Alicia has 20 gumballs. Pedro has that many gumballs plus an additional number of gumballs equal to three times the number Alicia has. They put their gumballs in a bowl, and later Pedro takes out 40% of the gumballs to eat. How many gumballs are remaining in the bowl? Let's answer step by step:

If Pedro has three times more gumballs than Alicia, he has 3 * 20 gumballs = 60 gumballs more. In total, Pedro has 20 gumballs + 60 gumballs = 80 gumballs. When they put their gumballs together, the total number of gumballs in the bowl becomes 20 gumballs + 80 gumballs = 100 gumballs. Pedro takes out 40% of the gumballs which is 40 / 100 * 100 gumballs = 40 gumballs. The number of gumballs remaining is 100 gumballs - 40 gumballs = 60 gumballs. The answer: 60.
