Final answer:
The expression that represents this is c + 4.
Step-by-step explanation:
To find the total number of baby chicks hatched, we need to add the number of chicks that hatched in the morning to the number of chicks that hatched in the afternoon.
The expression that represents this is:
Total number of chicks hatched = Number of chicks hatched in the morning + Number of chicks hatched in the afternoon
Since there were c baby chicks hatched in the morning, the expression becomes:
Total number of chicks hatched = c + 4
So, the expression that shows how many baby chicks hatched in all is c + 4.
