Answer :
Answer:
The answer is 23 elephants
Step-by-step explanation:
Firstly, we have to subtract 8 elephants to the total amount of elephants that there are in the wild life reserve.
These 8 elephants were born during summer, not before, and the question is about the total amount of elephants before summer.
So, the mathematical operation is:
Elephants after summer=31
Elephants were born during summer=8
Elephants before summer=31-8=23
Finally, the total amount of elephants before summer are 23.
