13,895.98
01/28
13,881.93
01/29

Which best represents the greatest amount of change that took place from one day to the next day over the four-day period?
a loss of 93.98 points
a loss of 72.47 points
a gain of 72.47 points
a gain of 93.98 points

Answer 1

To determine the greatest amount of change from one day to the next, we can calculate the changes day-to-day based on the given closing amounts:

1. From 01/27 to 01/28:
Change = 13,881.93 - 13,895.98 = -14.05 points (loss)

2. From 01/28 to 01/29:
Change = 13,954.40 - 13,881.93 = +72.47 points (gain)

3. From 01/29 to 01/30:
Change = 13,860.42 - 13,954.40 = -93.98 points (loss)

Now, let's summarize the changes:
- From 01/27 to 01/28: -14.05 points
- From 01/28 to 01/29: +72.47 points
- From 01/29 to 01/30: -93.98 points

The greatest change from one day to the next is a gain of 72.47 points from 01/28 to 01/29.

Therefore, the correct answer is:
**a gain of 72.47 points**.
