To find the percent decrease, you can use the following formula:
\[ \text{Percent Decrease} = \frac{\text{Original Price} - \text{New Price}}{\text{Original Price}} \times 100 \]
Given:
- Original Price = $60
- New Price = $54
First, find the amount of decrease:
\[ \text{Decrease} = 60 - 54 = 6 \]
Now, plug this into the formula:
\[ \text{Percent Decrease} = \frac{6}{60} \times 100 \]
\[ \text{Percent Decrease} = 0.1 \times 100 = 10% \]
So the percent decrease is 10%.
The answer is B 10%.
