Percentage Increase Calculation:
Percentage Increase = [(Enrollment in 2020 - Enrollment in 2019) / Enrollment in 2019] * 100
School A:
- Increase: 2140 - 1720 = 420
- Percentage Increase: (420 / 1720) * 100 ≈ 24.42%
School B:
- Increase: 1550 - 1390 = 160
- Percentage Increase: (160 / 1390) * 100 ≈ 11.51%
School C:
- Increase: 1300 - 1060 = 240
- Percentage Increase: (240 / 1060) * 100 ≈ 22.64%
School D:
- Increase: 1550 - 1330 = 220
- Percentage Increase: (220 / 1330) * 100 ≈ 16.54%
Comparing Percentage Increases:
- School A: 24.42%
- School B: 11.51%
- School C: 22.64%
