D) 2

Answer 1

The total change in the value of the stock over the course of the week is -1/8 point.

Step-by-step explanation:

To find the total change in the value of the stock over the course of the week, we need to add up the changes on each day. Let's calculate:

Change on Tuesday: -1/2 point

Change on Wednesday: +3/4 point

Change on Thursday: -3/8 point

To find the total change, we add these values:

-1/2 + 3/4 - 3/8 = -1/2 + 6/8 - 3/8 = -1/2 + 3/8 = -4/8 + 3/8 = -1/8

Therefore, the total change in the value of the stock over the course of the week is -1/8 point.
