**Steve**, Saturday, September 14, 2013 at 4:00pm(a) 0, since there are still 30 students in neither class. Only if the two classes sum to more than 150 does it mean that someone is taking both.

(b) 30, since that would mean that ALL the biology students are also taking algebra

(c) 60, since if all 30 biology students were taking algebra, that only uses up 90 of the 150 students.
