The value of n is 15.

The value of n is determined to be 15 based on the calculations provided in the context of the problem.

A) 15

This option is correct as it directly aligns with the calculated value of n based on the given mathematical expression or context, confirming that all operations lead to this result.

B) 20

Option B is incorrect because it suggests a value that does not match the computed results. The calculations leading to the value of n do not support this figure, indicating a misunderstanding or miscalculation.

C) 25

This option is also incorrect as it does not reflect the correct value derived from the problem context. The calculations clearly indicate that n does not equal 25, thus making this choice invalid.

D) 30

Option D is incorrect since it exceeds the value established through the given mathematical context. This number does not correspond to any calculations leading to the determination of n, thereby disqualifying it as a valid answer.

Conclusion

The correct answer is definitively 15, as it is the only option that accurately represents the value of n derived from the problem. All other options misrepresent the calculations and are therefore invalid, confirming that option A is the sole correct response.
