Answer:
The answer is 260 campers.
Step-by-step explanation:
If 15% liked swimming(39 people), you need to see how many times 15% can go into 100% with whole numbers. It is 6 times. (15x6=90). Do 39 campers times 6 = 234. Now there is 10% remaining. Well 10 is two thirds of 15(5+5=10add another 5 to get 15). So now you need to find what two thirds of 39 is. Simple! Do 39/3=13. 13+13=26(13 is ONE THIRD of 39. Multiply it by 2 and it would be TWO THIRDS).
Okay, we have 234 + 26 = 260!!!
