To analyze the function \( m = \frac{25x + 50}{x + 50} \), we first consider the variables involved:
1. \( x \) represents the volume of water mixed in milliliters and must be greater than or equal to 0 (i.e., \( x \geq 0 \)).
2. The function measures the saline concentrate in milliliters, which must be positive and logically limited to maximum values based on the mixture.
To determine the constraints for \( m \):
- The minimum value occurs when \( x = 0 \):
\[
m = \frac{25(0) + 50}{0 + 50} = \frac{50}{50} = 1
\]
- The maximum value occurs as \( x \) approaches infinity. As \( x \) becomes very large, the term \( \frac{25x}{x} \) approaches 25. Thus:
\[
\text{As } x \to \infty, \, m \to 25
\]
Therefore, the saline concentrate \( m \) will range from 1 to 25 (not inclusive), as we cannot physically have an infinite concentration of saline. The value of \( m \) is restricted to **"positive numbers between 1 and 25"**.
The complete constraint on the variable \( m \) can be written as:
**"1 < m < 25".**
