Question

There are 50 total students in the 12th grade at bayside high. thirty three students are enrolled in ap calculus and twenty seven are enrolled in ap english. three students are enrolled in neither ap class. how many students are enrolled in only ap calculus?

Answer 1

50 - 3 = 47 - the number of students who are enrolled in ap calculus or in ap english

33 + 27 = 60

60 - 47 = 13 - the number of students who are enrolled in ap calculus and in ap english.
Therefore the number of students who are enrolled in only ap calculus is equal
33 - 13 = 20
