What happens to the value of the expression n+15 as n decreases? Choose 1 answer: A It increases. (B) It decreases. (C) It stays the same.

Consider Expression Change: Let's consider the expression n + 15. If n decreases, we are essentially subtracting a certain amount from n. Since 15 is a constant and does not change, the only variable part of the expression is n. When n decreases, the whole value of the expression n + 15 must also decrease because we are adding a smaller number to 15.Illustrative Example: To illustrate this with an example, if n decreases from 10 to 5, the expression changes as follows: For n = 10, the expression n + 15 equals 10 + 15 = 25. For n = 5, the expression n + 15 equals 5 + 15 = 20. We can see that as n decreased by 5, the value of the expression also decreased by 5.Correct Answer Explanation: Therefore, the correct answer to the question is that the value of the expression n + 15 decreases as n decreases. This corresponds to option (B) It decreases.

Consider Expression Change: Let's consider the expression $n + 15$ . If $n$ decreases, we are essentially subtracting a certain amount from $n$ . Since $15$ is a constant and does not change, the only variable part of the expression is $n$ . When $n$ decreases, the whole value of the expression $n + 15$ must also decrease because we are adding a smaller number to $15$ .
Illustrative Example: To illustrate this with an example, if $n$ decreases from $10$ to $5$ , the expression changes as follows: $\newline$ For $n = 10$ , the expression $n + 15$ equals $10 + 15 = 25$ . $\newline$ For $n = 5$ , the expression $n + 15$ equals $5 + 15 = 20$ . $\newline$ We can see that as $n$ decreased by $5$ , the value of the expression also decreased by $5$ .
Correct Answer Explanation: Therefore, the correct answer to the question is that the value of the expression $n + 15$ decreases as $n$ decreases. This corresponds to option (B) It decreases.
