Valentin Sellers · Answer 1

10 students take both 8 students take only algebra i and 10 students take only algebra 2 Add these three groups together to get 28. 60-28=32 who take neither of the classes

Marcus Fuentes · Answer 2

Out of the total 60 students 18 take Algebra 1 and 20 take Algebra II. 10 take both. So out of the 18 taking algebra 10 are taking Algebra II. If we don't count that 10 because they are already counted in Algebra II count. So 28 students are taking either course. Therefore 60-28 = 32 students who are not taking either of these courses
