A company's stock price fluctuated over a period of four days. The table shows the change in stock price per day.

DayChange

1

increased by $3.50

2

decreased by $3.70

3

increased by $3.30

4

decreased by $3.40

 The net change in the company’s stock price over the four days is $

To find the net change in the company’s stock price over the four days, we need to sum up the changes for each day:

1. Day 1: increased by $3.50 → $ +3.50 $
2. Day 2: decreased by $3.70 → $ -3.70 $
3. Day 3: increased by $3.30 → $ +3.30 $
4. Day 4: decreased by $3.40 → $ -3.40 $

Now, let's add these changes together:

\[
\text{Net Change} = 3.50 - 3.70 + 3.30 - 3.40
\]

Calculating this step-by-step:

\[
3.50 - 3.70 = -0.20
\]
\[
-0.20 + 3.30 = 3.10
\]
\[
3.10 - 3.40 = -0.30
\]

The net change in the company’s stock price over the four days is $-0.30$ dollars.
