USPshnik [31]

Answer:

31 servings

Yes there would be leftover

Step-by-step explanation:

In this question, we are asked to calculate the amount of a certain volume that would be had and if there also would be leftovers.

Firstly, to solve this question, we need to know the total volume made by the siblings.

Let’s convert What Jeniffer made to liters. It must be known that 1000ml is 1L. This means her 5L would be 5 * 1000 = 5000ml

Let’s add this to what her brother has and it would be 5000 + 750 = 5,750ml

Now they made a series of 180ml servings. We need to know how many of these would they have. We simply make a division: 5,750/180 = 31.94

There would be 31 of this and also there would be a remainder
