If the present ages of Mike and John are n (<80) years and m years respectively, which of the following expressions is true if the policy will mature exactly x years from today?
A. \(n+m+x=80\)
B. \(n+2m+x=80\)
C. \(n+m+2x=80\)
D. \(2(n+m)+x=80\)
E. \(n-m+2x=80\)

E. \(n-m+2x=80\)
Given: The policy will mature exactly x years from today
Mike's age in x years = n + x
John's age in x years = m + x
So, when the policy matures, the sum of their ages = (n + x) + (m + x)
Since the policy matures when the sum of their ages is 80, we can write: (n + x) + (m + x) = 80
Simplify to get: n + m + 2x = 80
Answer: C

Current age of Mike = \(n\) years
Current age of John = \(m\) years
Policy will mature in \(\textbf{x}\) years from today.
Age of Mike after \(\textbf{x}\) years = \(n + x\) years
Age of John after \(\textbf{x}\) years = \(m + x\) years
Policy will mature when Age of Mike + Age of John = 80
\((n + x) + (m + x) = 80\)
\(\textbf{n + m + 2x = 80}\)
Hence, Answer is C
Current age of John = \(m\) years
Policy will mature in \(\textbf{x}\) years from today.
Age of Mike after \(\textbf{x}\) years = \(n + x\) years
Age of John after \(\textbf{x}\) years = \(m + x\) years
Policy will mature when Age of Mike + Age of John = 80
\((n + x) + (m + x) = 80\)
\(\textbf{n + m + 2x = 80}\)
Hence, Answer is C
