Case Study

Retail Register Discrepancy Comparison

Based on the scenario above, write an explanation that helps the clerk by recalling the step-by-step mathematical rules for simplifying absolute value expressions. In your response:

  1. Recall and state the simplified value of the absolute value expression $|-2|$ and explain what absolute value represents.
  2. Recall and state how the negative sign outside the absolute value bars affects that value, writing the final simplified integer for Register B's adjustment of $-|-2|$.
  3. Compare the final simplified integer of Register B's adjustment to Register A's adjustment of 2 dollars, and state which register had the greater adjustment using an inequality statement.
