25 from year 7
55 from year 8
answer 80
there you go
80 students joined the league
8th grade: 1/6 * 330 = 55
7th grade: 10% (0.10) * 250 = 25
55 + 25 = 80
55 of 8th and 25 of 7th i.e 80 students in the league
From 8th Grade:
1/6 * 330 = 55 students
From the 7th Grade:
10% expressed as 10/100, so:
10/100 * 250 = 25 students
Therefore, the total students in the bowling league is:
55 + 25 = 80 students
Hope this helps.
