To determine how many sisters Sally has, let's analyze the information step by step:

Sally is a girl, and she has 3 brothers.
This means there are 3 boys in the family (her brothers).
Each brother has 2 sisters.
From the perspective of any one brother, he sees 2 girls in the family.
Since Sally is one of the girls, there must be one more girl besides Sally to make up the 2 sisters each brother counts.
Total number of girls in the family:
- Sally (1 girl)
- The other sister (1 girl)
  Total = 2 girls
How many sisters does Sally have?
Sally herself is one of the girls, so the number of sisters she has is the other girl(s).
Since there are 2 girls total and Sally is one, she has 1 sister.

Answer: Sally has 1 sister.

I need to work through this step-by-step.

Given information:

Sally is a girl
Sally has 3 brothers
Each brother has 2 sisters

Since Sally is one of the sisters that each brother has, and each brother has 2 sisters total, that means th ere must be exactly 2 sisters in the family.

The 2 sisters are:

Sally
One other sister

Therefore, Sally has 1 sister.
