Answer:
69 or 71, read below for details.
Step-by-step explanation:
This is unfinished, but I'll answer to my best ability.
200 seniors graduated
99 in band
30 students in art were NOT in band.
I assume the question here is either how many students were in band and art, which would be 69 as 99 - 30 = 69.
If the question is how many students didn't take any electives, the answer is 200 - 99 - 30 = 71.
