Answer:

75

Step-by-step explanation:

Im sorry if this wrong I tryed I think this right not sure

Answer:

D

Step-by-step explanation:

15 out of 90

Divide both sides by 15

1 out of 6

It is reasonable to assume that the ratio 1:6 will be consistent

1:6

Multiply both sides by 20 to get 120 students

20 : 120

20 people have a Galaxy S21 out of 120, so 120-20, which is 100 don't have a Galaxy S21.

The answer is 100.

Hope this helps :)

Have a great day!
