Answer:
40 servings.
Step-by-step explanation:
First we need to know the relation between pint and cup, and between oz and cup:
1 pint = 2 cup
8 oz = 1 cup
Now, we have that each batch has 16 fluid oz of lemon juice and 4 pints of orange juice, that is, 2 cups of lemon juice and 8 cups of orange juice, in a total of 10 cups.
If we have 4 batches, we have a total of 4 * 10 = 40 cups
So if each serving is 1 cup, the total made is equal to 40 servings.
