At a people counting station, the number of people counted on the first day was twice the total number counted on the second day. If 500 people were counted on the second day, how many people were counted on the two days? Let's think first. Chain of thought:
There were 2 * 500 = 1000 people at the counting station who were counted on the first day. In the two days, 1000 + 500 = 1500 were counted at the station.
Therefore, the answer is 1500.
