7+9-5 = 11 are either old or favorite or both.
So, 114 are neither

To find the number of cats that are neither old nor favorite, we need to subtract the number of cats that are old, favorite, or both from the total number of cats.
Let's break down the information given:
- Total number of cats: 125
- Number of cats that are old: 7
- Number of cats that are her favorite: 9
- Number of cats that are both old and favorite: 5
To find the number of cats that are neither old nor favorite, we can calculate it step by step:
1. Calculate the number of cats that are either old or favorite: old cats + favorite cats - cats that are both
= 7 + 9 - 5
= 11
2. Subtract the number of cats that are either old or favorite from the total number of cats:
Total cats - (old or favorite cats)
= 125 - 11
= 114
Therefore, there are 114 cats that are neither old nor favorite.
