To calculate the percent decrease in the value of the car, you can use the following formula:
\[
\text{Percent Decrease} = \left(\frac{\text{Original Value} - \text{New Value}}{\text{Original Value}}\right) \times 100
\]
In this case, the original value is $18,000 and the new value is $15,300.
1. Calculate the decrease in value:
\[
\text{Decrease} = 18,000 - 15,300 = 2,700
\]
2. Now plug the decrease and original value into the percent decrease formula:
\[
\text{Percent Decrease} = \left(\frac{2,700}{18,000}\right) \times 100
\]
3. Calculate the fraction:
\[
\frac{2,700}{18,000} = 0.15
\]
4. Convert it to a percentage:
\[
0.15 \times 100 = 15\%
\]
Thus, the percent decrease is **15%**.
The correct answer is **B**.
\[
\text{Percent Decrease} = \left(\frac{\text{Original Value} - \text{New Value}}{\text{Original Value}}\right) \times 100
\]
In this case, the original value is $18,000 and the new value is $15,300.
