CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. Heaviest = 5.0 kg, lightest = 2.8 kg.

  2. Range = 5.0−2.8=2.25.0 - 2.8 = 2.2 kg.

Worth noting

1.8 kg uses the first weight listed, 3.2 kg, as the lightest. 0.6 kg subtracts the two largest weights. 5 kg is the heaviest weight, not the range.
