Q. When the value of UZX Technology stock fell 55 points, the change was represented online as −5-5 points.\newlineThe next day, the change in value of the stock was represented as 77 points. Which of these describes the change in the stock's value?\newlineChoices:\newline(A)It fell 77 points.\newline(B)It neither rose nor fell.\newline(C)It rose 77 points.
  1. Analyze Stock Value Changes: Step 11: Analyze the changes in stock value over two days.\newlineFirst day change: −5-5 points (stock value fell by 55 points).\newlineSecond day change: +7+7 points (stock value rose by 77 points).
  2. Calculate Total Change: Step 22: Calculate the total change over the two days.\newlineTotal change = (−5)+7(-5) + 7\newlineTotal change = 22 points.
