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%.
