A school math club has 70 students and a science club has 95 students

1.	A school math club has 70 students and a science club has 95 students as members. If 45 children are members of only one club, what is the number of children joining both clubs?
Answer» Step-by-step explanation: To have students belonging to both clubs, the both club must have equal seats available as each student will take 2 seats(one for MATH and another for science). Now the maximum number of students is 15. Now if we add both math and science clubs seats(amount of MEMBERS available) we GET 27. 13 of the slots are taken by single club members. This LEAVES 27–13 = 14 seats available. Now each student will get 2 seats, therefore the number of students that joined both clubs is 14/2 = 7. 7 students joined both clubs.
