Total Student Enrollment (Boys + Girls):

School A:

  • 2019: 6.5 (boys) + 10.7 (girls) = 17.2 (hundreds) = 1720
  • 2020: 9.5 (boys) + 11.9 (girls) = 21.4 (hundreds) = 2140

School B:

  • 2019: 7.4 (boys) + 6.5 (girls) = 13.9 (hundreds) = 1390
  • 2020: 8.6 (boys) + 6.9 (girls) = 15.5 (hundreds) = 1550

School C:

  • 2019: 6.3 (boys) + 4.3 (girls) = 10.6 (hundreds) = 1060
  • 2020: 7.6 (boys) + 5.4 (girls) = 13.0 (hundreds) = 1300

School D:

  • 2019: 6.5 (boys) + 6.8 (girls) = 13.3 (hundreds) = 1330
  • 2020: 7.9 (boys) + 7.6 (girls) = 15.5 (hundreds) = 1550

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%
  • School D: 16.54%

The school with the minimum percentage increase is School B.
