Answer 1

To find the percent of decrease in the number of cars, we can use the following formula:

\[
\text{Percent Decrease} = \left( \frac{\text{Old Number} - \text{New Number}}{\text{Old Number}} \right) \times 100
\]

In this case, the old number of cars is 64 and the new number is 48.

First, we calculate the difference in the number of cars:

\[
\text{Difference} = 64 - 48 = 16
\]

Next, we plug the values into the percent decrease formula:

\[
\text{Percent Decrease} = \left( \frac{16}{64} \right) \times 100
\]

Calculating \( \frac{16}{64} \):

\[
\frac{16}{64} = 0.25
\]

Now, multiply by 100:

\[
0.25 \times 100 = 25
\]

Thus, the percent of decrease in the number of cars is \( \boxed{25\%} \).
