Question

The closing amount of the Dow Jones Industrial Average on the stock market for four days is shown in the table below.

Date
Closing amount (in points)
01/27
13,895.98
01/28
13,881.93
01/29
13,954.4
01/30
13,860.42

Which best represents the greatest amount of change that took place from one day to the next day over the four-day period?

Answer 1

simply calculate the day-to-day changes (there are 4 days, so there will be 3 day-to-day changes). it wants the greatest amount of change (so consider the magnitude of increases and decreases)

for example, the decrease from 1/27 to 1/28 can be calculated via:

13,895.98 - 13,881.93

continue w/ the same logic for the rest of the problem.
