The number of students that are in favor of this idea are: 518

Since 2/5 of the students are seniors. Then:
Number of Seniors = (2/5) * 3700
Number of Seniors = 1480
Number that are not seniors = 3700 - 1480 = 2220
4/5 of the seniors are opposed to the school forming a rock climbing team. Thus:
Number of seniors that don't like rock climbing = (4/5) * 1480 = 1184
9/10 of the remaining students (not seniors) are also opposed to forming a rock climbing team. Thus:
(9/10) * 2220 = 1998
The number of students that are in favor of this idea are:
3700 - (1184 + 1998) = 518 like rock climbing
Complete question is:
There are 3700 students at Canyon High School and 2/5 of these students are seniors.
If 4/5 of the seniors are opposed to the school forming a rock climbing team and 9/10 of the remaining students (not seniors) are also opposed to forming a rock climbing team,
how many students are in favor of this idea?
