A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
The total weight of m peanuts at a weight of (n + 3) milligrams eachTotal weight = (m)(n + 3)
The total weight of n almonds at a weight of (m + 3) milligrams eachTotal weight = (n)(m + 3)
So, we have:
Quantity A: (m)(n + 3)
Quantity B: (n)(m + 3)
Expand both quantities:
Quantity A: mn + 3m
Quantity B: nm + 3n
Subtract mn (aka nm) from both quantities:
Quantity A: 3m
Quantity B: 3n
Divide both quantities by 3 to get:
Quantity A: m
Quantity B: n
Since we are not given any information about the value of m and n, the correct answer must be D
Cheers,
Brent
