Question

In a group of 60 students, 18 students take algebra i, 20 students take algebra ii, and 10 students take both subjects. how many students don't take either of these subjects?

Answer 1

Answer:

  32

Step-by-step explanation:

The number that take algebra i includes those who take both subjects, as does the number taking algebra ii. Then the number taking algebra i alone is ...

   18 -10 = 8 . . . . . take only algebra i

So the number taking any kind of algebra is ...

  20 + 8 = 28

and the number not taking either subject is ...

  60 -28 = 32 . . . not taking either subject
