Answer:
3450
Explanation:
To find out how many students are opposed to forming a debate team, you can subtract the number of students in favor from the total number of students.
First, find the number of seniors who are in favor:
35 seniors are in favor.
Now, find the number of non-seniors who are in favor:
There are 3500 total students, and 14 are seniors, so there are 3500 - 14 = 3486 non-seniors.
Out of these non-seniors, 15 are in favor.
Now, add the number of seniors and non-seniors who are in favor:
35 (seniors) + 15 (non-seniors) = 50 students in favor.
Finally, subtract this number from the total number of students to find how many are opposed:
3500 (total students) - 50 (in favor) = 3450 students are opposed to forming a debate team.
So, 3450 students are opposed to this idea.
