1. The problem states: Mail's water bottle has 24 ounces initially. After she drinks $x$ ounces, the amount left is expressed. 2. We want to find expressions that correctly represent the relationship between the initial amount, the amount drunk, and the amount left. 3. The initial amount is 24 ounces. 4. After drinking $x$ ounces, the remaining amount is $24 - x$ ounces. 5. Let's analyze each option: - A. $24 \div 10 = x$ means dividing 24 by 10 equals $x$, which does not represent the amount left after drinking $x$ ounces. - B. $24 + 10 = x$ means adding 10 to 24 equals $x$, which is incorrect for this context. - C. $24 - 10 = x$ means subtracting 10 from 24 equals $x$. This matches the idea that after drinking 10 ounces, $x$ is the amount left. This expression is correct if $x$ represents the amount left. - D. $x + 10 = 24$ means the amount drunk plus 10 equals 24, which could be correct if $x$ is the amount drunk and 10 is the amount left, but the problem states $x$ is the amount drunk, so this is not consistent. - E. $10x = 24$ means 10 times $x$ equals 24, which is unrelated. 6. Therefore, the expressions that represent the situation are: - $24 - x$ (amount left after drinking $x$ ounces) - $x + \text{(amount left)} = 24$ (total amount) 7. From the options, only C and D correctly represent the situation depending on what $x$ stands for. Final answer: C and D are correct expressions representing the situation.
