The stock of Company A gained $3.45 throughout the day and ended at a value of $72.45. By what percentage did the stock rise?

Answer 1

To find the percentage increase in the stock price, we can use the formula:

$$\text{Percentage Increase}=\left(\frac{\text{Increase in Value}}{\text{Original Value}}\right)\times 100$$

1. Identify the increase in value: The stock gained $3.45.
2. Determine the original value: The ending value of the stock is $72.45. Therefore, the original value is calculated by subtracting the increase from the ending value:

$$\text{Original Value}=72.45-3.45=69.00$$

3. Calculate the percentage increase:

$$\text{Percentage Increase}=\left(\frac{3.45}{69.00}\right)\times 100$$

4. Perform the calculation:

$$\text{Percentage Increase}=\left(0.05000\right)\times 100\approx 5.00$$

Thus, the stock rose by approximately 5.00%.
