Answer :

Final answer:

Upon evaluating the expression y = 25(1 - 2) (7(-22)ts - 2² + 5) and ignoring the typo 'ts,' we find that y equals -25, which matches answer choice B.

Explanation:

The value of y when y = 25(1 - 2) (7(-22)ts - 2² + 5) is actually quite simple to find once we identify the potential typo in the question. The expression within the parentheses appears to contain a typo, 'ts,' which we will ignore as instructed. Additionally, since the remainder of the expression does not contain a variable, we can conclude that y is independent of any variables outside the scope of this expression.

Here is the step-by-step evaluation of the expression:

  1. Resolve the innermost parentheses: 1 - 2 = -1
  2. Calculate the power: 2² = 4
  3. Subtract the square from 5: 5 - 4 = 1
  4. As there is no variable 'ts' and we cannot resolve the term 7(-22)ts, we ignore this term as instructed.
  5. Multiply the remaining terms with 25: 25 * -1 * 1 = -25

As a result, y = -25, which corresponds to answer choice B.
