The average (arithmetic mean) of m and n is 1 more than k

A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Kudos for the right answer and explanation
We can write: (average of m and n) \(= k + 1\)
This means: \(\frac{m+n}{2} = k + 1\)
Multiply both sides by 2 to get: \(m+n = 2k + 2\)
GIVEN:
QUANTITY A: \(m+n\)
QUANTITY B: \(2k+1\)
Replace \(m+n\) with \(2k + 2\) to get:
QUANTITY A: \(2k+2\)
QUANTITY B: \(2k+1\)
Subtract \(2k\) from both quantities to get:
QUANTITY A: \(2\)
QUANTITY B: \(1\)
Answer: A
Cheers,
Brent
