The corret anwser is actually going to be false! Your math teacher is wrong!
Tbh I would say ounces or grams. I wouldn't make a final decision on my answer though.

You simply use this operation:
- total students are 305, we need to find how many of thm play instrumenst if 40% does.
40% can be rewrited as 0,4 in decimal.
than we simply utilise a basic percentage operation which allows us to find A PART of somethin=>
305×0,4= students who instruments.
Its C! Hope this helps and can you mark me as brainliest :))
Are you going to tell me what you meant by that? when you messaged me?
