Let c represent the number of children.

Which expression represents the number of parents?

Answer 1

Answer: if there is a option that say c - 9

Step-by-step explanation: that is the right one i got it as that in the quiz

Answer 2

the number of parents is c -9 since there are 9 more children than parents
And we know that the total number of people in the room is 25 so:
c + c-9 = 25
or
2c - 9 = 25
We can then solve for c
2c = 34
c = 17
