A school has 1,200 students enrolled at the beginning of the year.

By mid-year, enrollment had decreased to 1,080 students. What was the percent decrease?


To calculate the percent decrease in enrollment, we can use the formula:

\[
\text{Percent Decrease} = \frac{\text{Initial Value} - \text{Final Value}}{\text{Initial Value}} \times 100
\]

In this case:
- Initial Value = 1,200
- Final Value = 1,080

Now, applying the values:

\[
\text{Percent Decrease} = \frac{1,200 - 1,080}{1,200} \times 100
\]
\[
\text{Percent Decrease} = \frac{120}{1,200} \times 100 = 10\%
\]

So, the percent decrease in enrollment is **10%**.

Here are some related questions for further practice:
1. If the school had started with 1,500 students, what would the percent decrease be for the same drop to 1,080?
2. What is the percentage decrease if the final enrollment was 960 students instead of 1,080?
3. How would you calculate the percent increase if the number of students increased to 1,320 from 1,200?
4. If the percent decrease had been 15%, what would the final enrollment be?
5. What would the enrollment be if there was a 20% decrease from 1,200?

**Tip:** When calculating percent decrease or increase, always subtract the final value from the initial value before dividing by the initial value.
