The correct answer is: 9 + c = 12
Further explanation:
Given
c = number of babies whose eyes are closed
So,
If the total number of babies are 12 then the sum of babies with eyes closed and eyes opened should be equal to 12.
As c is the number of babies with eyes closed and 9 is the number of babies with eyes opened then,
The equation can be used to find the number of babies whose eyes are open
Three babies have their eyes closed in the photograph.
