Hey guys, could you please tell me if I did 2a correctly? I am doubting myself on everything.
I did integral from 0 to 3 of (f(t) minus 250)
and then integral from 0 to 7 of (f(t) minus 2000)
added those together.

Is it right?

And on 2b, intead of using the notation U(union) I used words for my answer. I said amount of water is decreasing from time t=blah blah blah to t=blah blah blah and from t=blah blah blah to t=blah blah blah.
Is that okay?

I would appreciate it if you guys respond.
