Answer: Everybody will need to pay 3.18 dollars. ($3.18)
Step-by-step explanation:
To find out equal amounts of money, you need to divide the total cost by how many people there are. The total cost, in this case, is 12.72, and the amount of people in this problem is 4 people. That means, if everybody were to pay the same amount, you would need to divide 12.72 by 4.
12.72/4=3.18
