8 fluid oz = 1 cup
16 fluid oz of lemon juice=2 cups of lemon juice
(8/16 = 1/x ;*cross multiply* 8x = 16 ; x = 2)
1 pint = 2 cups
3 pints of orange juice = 6 cups of orange juice
(1/3 = 2/x ;*cross multiply* 1x = 6 ; x = 6)
So, 1 batch makes 8 cups of punch.
2 cups of lemon + 6 cups of orange = 8 cups
4 batches would make 32 cups of punch.
Each serving is 1 cup and he made 32 cups of punch, therefore
he made 32 servings all together.
