In a class of 50 students, 28 participate in MATHCOUNTS, 21 participate in science club, and 6 students participate in neither. How many students participate in both MATHCOUNTS and science club?

50-6=44 students participate in at least some activity...

Let y be the number of students who participate in both MATHCOUNTS and the science club.

(28-y)+(21-y)+y=44

 

49-y=44

 

y=5.

 

Five(5) students participate in both MATHCOUNTS and science club.
