Solution:
We are given the equation -25 + 19 + n = s, which can be simplified to -6 + n = s. We must determine the value of n.
Statement One Alone:
s = 2
Since we know s = 2, we can substitute 2 for s in the equation -6 + n = s.
-6 + n = 2
n = 8
Statement one alone is sufficient to answer the question. We can eliminate answer choices B, C, and E.
Statement Two Alone:
n/s = 4
We can rewrite the equation n/s = 4 by multiplying both sides of the equation by s.
n = 4s
Since n = 4s, we can substitute 4s for n in the equation -6 + n = s.
-6 + 4s = s
-6 = -3s
s = 2
Now we can determine the value of n.
-6 + n = s
-6 + n = 2
n = 8
Statement two alone is sufficient to answer the question.
