To calculate the percent discount given, you can use the formula:
\[ \text{Percent Discount} = \left( \frac{\text{Original Price} - \text{Sale Price}}{\text{Original Price}} \right) \times 100 \]
Using the values given:
- Original Price = $79
- Sale Price = $65
First, calculate the difference:
\[ \text{Discount Amount} = 79 - 65 = 14 \]
Now, substitute this back into the formula:
\[ \text{Percent Discount} = \left( \frac{14}{79} \right) \times 100 \]
Calculating \( \frac{14}{79} \):
\[ \frac{14}{79} \approx 0.1772 \]
Now multiplying by 100 to get the percentage:
\[ 0.1772 \times 100 \approx 17.72% \]
Rounding this value gives approximately 18%.
Thus, the percent discount given is:
A. 18%
