Explanation
This is an algebraic translation question, so start by translating the given information into equations. Remember to add 8 to both Polly and Quan’s ages, because they will both be 8 years older in 8 years!
\(p + 8 = 2(q + 8)\)
\(p + 8 = 2q + 16\)
\(p = 2q + 8\)
\(p - 8 = 2q\)
Hence option C is correct!
