Here,
BOYS::
No. of boys enrolled in Spanish = 12
Not enrolled in Spanish = 19,
2 boys those are not enrolled in Spanish decide to enroll in Spanish, total enrolled in Spanish = 12 + 2 = 14
Again
7 additional boys join and enrolled themselves in Spanish, total enrolled in Spanish = 14 + 7 = 21
and the total boys not enrolled in Spanish = 17
Total Boys at Millbrook High school = 21 + 17 = 38
GIRLS
No. of girls enrolled in Spanish = 13
Not enrolled in Spanish = 16,
Again,
8 additional girls join and enrolled themselves in Spanish, total enrolled in Spanish = 13 + 8 = 21
and the total girls not enrolled in Spanish = 16
Total girls at Millbrook High school = 21 + 16 = 37
Total students = 37 + 38 = 75
Total students enrolled in Spanish = 21 + 21 = 41
therefore, the percent of 9th grade students at Millbrook would then be enrolled in Spanish = \(\frac{41}{75} *100\)% = 56%
