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 the number of students, we can use the following formula:

\[
\text{Percent Decrease} = \frac{\text{Original Number} - \text{New Number}}{\text{Original Number}} \times 100
\]

In this case:
- The original number of students is 1,200.
- The new number of students is 1,080.

Substitute these values into the formula:

\[
\text{Percent Decrease} = \frac{1,200 - 1,080}{1,200} \times 100 = \frac{120}{1,200} \times 100 = 0.1 \times 100 = 10\%
\]

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

2. What would the new enrollment be if the decrease had been 15% instead of 10%?
3. How many students would need to enroll mid-year to return the enrollment to 1,200?
4. What is the percentage decrease if the enrollment dropped from 1,080 to 1,000 students?
5. If the school started with 1,500 students instead of 1,200, what would a 10% decrease look like?
