Final answer:
The correct expression to calculate how many flyers each of Armando's friends received is (400 – 200) : 4, which simplifies to 200 divided by 4.
Step-by-step explanation:
The correct expression to calculate how many flyers Armando gave each friend is:
(400 - 200) : 4
Here's the explanation:
400: Represents the total number of flyers Armando wants to give out.
200: Represents the number of flyers Armando gave out himself.
400 - 200: Represents the number of flyers remaining to be distributed among his friends.
4: Represents the number of friends who volunteered to help.
(400 - 200) : 4: This expression divides the remaining flyers (400 - 200) by the number of friends (4) to calculate how many flyers each friend receives.
Therefore, (400 - 200) : 4 is the correct expression to calculate the number of flyers per friend.
