Answer 1

To calculate the percent decrease from 25 to 15, 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 25 and the New Value is 15.

1. Subtract the new value from the original value:
\[
25 - 15 = 10
\]

2. Now, divide the difference by the original value:
\[
\frac{10}{25} = 0.4
\]

3. Finally, multiply by 100 to get the percentage:
\[
0.4 \times 100 = 40
\]

Thus, the percent decrease from 25 to 15 is 40.0%.

So, the final answer rounded to the nearest tenth is:

\[
\boxed{40.0}
\]
