Explanation
When y = −1, Quantity A is −2 and Quantity B is −20. Eliminate choices (B) and (C). Plug in another value for y. When y = −100, Quantity A is −200 and Quantity B is −2,000. Quantity A is always greater.
Hence A is the correct option.

Another approach is to use matching operations
Quantity A: 2y
Quantity B: 20y
Subtract 2y from both quantities
Quantity A: 0
Quantity B: 18y
Divide both quantities by 18
Quantity A: 0
Quantity B: y
Since we're told that y < 0 (y is negative), we can conclude that quantity A is greater.
