Answer:

55 senior tickets

Step-by-step explanation:

400 seats

students: $8

Adults: $10

Seniors: $7

All seats were sold and the total money they got was $3,535

Adult tickets sold was 10 less than the # of student and seniors combined.

8a+10b+7c=3535

a+b+c=400 now just solve for them

8a+10b+7c=3535

-8a-8b-8c=-3200

2b-c=335...

If you solve for the numbers, you'll get 55 tickets.
