2 campers went rowing in the morning. 27 campers went rowing in the afternoon. How many more campers went rowing in the afternoon than in the morning?
There were 27 campers rowing in the afternoon. 
We know that 2 campers went rowing in the morning. 
We want to know how many more campers went rowing in the afternoon than in the morning. 

To solve this problem, we need to find out how many campers went rowing in the morning and subtract that number from 27. 

27 - 2 = 25 

Therefore, 25 more campers went rowing in the afternoon than in the morning.
