If 0.139 + 0.75 + 2.105 – (1.001) × 1.1 = 2 – k, then the value of k is

  1. A.0.8925
  2. B.0.982
  3. C.0.1071✓ Correct
  4. D.0.1075

Explanation

First compute 0.139 + 0.75 + 2.105 = 2.994. Then compute (1.001) × 1.1 = 1.1011. So the left side equals 2.994 − 1.1011 = 1.8929. Setting this equal to 2 − k, we get k = 2 − 1.8929 = 0.1071. Therefore, the value of k is 0.1071.
