Final answer:
To find out how much fruit punch each person will get, we divide the total amount of fruit punch by the number of friends. In this case, each person will get approximately 3.81 cups of fruit punch.
Step-by-step explanation:
To find out how much fruit punch each person will get, we need to divide the total amount of fruit punch by the number of friends. In this case, there are 5 gallons of fruit punch and 21 friends.
To convert gallons to cups, we know that 1 gallon is equal to 16 cups. So, 5 gallons is equal to 5 x 16 = 80 cups of fruit punch.
Now, to find out how much each person will get, we divide the total cups by the number of friends: 80 cups / 21 friends = approximately 3.81 cups per person. Therefore, each person will get approximately 3.81 cups of fruit punch.
