Question

In a group of 60 students, 14 students take Algebra 1, 20 students take Algebra 2, and 7 students take both subjects. How many students don't take either of these subject?

Answer 1

First we add all of the students that take either Algebra 1, Algebra 2 or both:
14+20+7= 41

Which means out of 60 students 41 take either Algebra 1, Algebra 2 or both
To find the rest of the students we subtract 41 from 60
60-41= 19

ANSWER:
19 students don't take either subject
