Which of the following options represents an approximate value for the question mark (?) in the following equation? 65.321 + 22.4 × 3.2 + ? = 502.871	Choose one.
A) 509.2  B) 529.2  C) 504.2  D) 549.2  E) 506.2
65.321 + 22.4 × 3.2 + ? = 502.871   or, ? = 502.871 – 65.321 + 22.4 × 3.2   ? = 502.871 – 65.321 + 71.68   ≈ 509.2   509.2nswer 509.2
