Question

What was the overall change in stock price?
A. $2
C. $22
B. -$2
D. -$22

Answer 1

To find the overall change in stock price, we need to calculate the total decrease and total increase in the stock price over the given periods.

1. **Decrease for 5 days:**
- Stock price decreased by $2 per day for 5 days:
\[
\text{Total decrease} = 5 \text{ days} \times -2 \text{ dollars/day} = -10 \text{ dollars}
\]

2. **Increase for 4 days:**
- Stock price increased by $3 per day for 4 days:
\[
\text{Total increase} = 4 \text{ days} \times 3 \text{ dollars/day} = 12 \text{ dollars}
\]

3. **Overall change in stock price:**
- Combine the total decrease and total increase:
\[
\text{Overall change} = \text{Total increase} + \text{Total decrease}
\]
\[
\text{Overall change} = 12 \text{ dollars} + (-10 \text{ dollars}) = 2 \text{ dollars}
\]

Thus, the overall change in stock price is **$2**.

The correct answer is **A. $2**.
