Bot GPT 4-o mini To calculate the percentage increase in the cost of the jacket, we can use the formula:
\[ \text{Percentage Increase} = \left( \frac{\text{New Price} - \text{Old Price}}{\text{Old Price}} \right) \times 100 \]
Given:
- Old Price = $95.00
- New Price = $109.25
Now, substitute the values into the formula:
\[ \text{Percentage Increase} = \left( \frac{109.25 - 95.00}{95.00} \right) \times 100 \]
First, calculate the difference in price:
\[ 109.25 - 95.00 = 14.25 \]
Now, divide by the old price:
\[ \frac{14.25}{95.00} \approx 0.15026315789 \]
Finally, multiply by 100 to get the percentage:
\[ 0.15026315789 \times 100 \approx 15.03% \]
Rounding to two decimal places gives approximately 15%. Therefore, the percentage increase of the cost of the jacket is:
B. 15%
