To understand the change in the stock's value based on the representations given:
- Yesterday, the stock lost 1 point (–1 point).
- The next day, the stock lost an additional 5 points (–5 points).
To calculate the total change in the stock's value over these two days:
- Day 1: Loss of 1 point (–1)
- Day 2: Loss of 5 points (–5)
Combining these changes gives: –1 + (–5) = –6 points.
This means the total change in the stock's value across both days is a loss of 6 points.
Therefore, the correct description of the change in the stock's value is: it lost 6 points.
However, among the options you provided, the closest is it lost 5 points, but it's important to note that the total change is actually 6 points if we consider both days combined. If we are to strictly adhere to the options you presented, then "it lost 5 points" would be the appropriate choice if referring to just the second day’s change.
