Solution
Logical reasoning:
The quantity of Beverages present at the store ;
Soda = 2000ml = 2L
Apple Juice = 2.5L
Fruit Punch = 1.5L
Lemonade = 2L
We have to buy exactly 10 liters but it should be at least one container of each beverage.
Soda + Apple juice + Fruit Punch + Lemonade = 8L
So we need 2 L more.
The only way of doing this is by either having 2 container of soda or 2 container of lemonade.
Therefore
The combination of beverages she can purchased;
Soda = 2 container
Apple juice = 1 container
Fruit punch= 1 container
Lemonade = 1 container
