Answer:
The number of people that can be served with 40 spring rolls depends on the portion size and how many spring rolls each person would eat.
Let's assume that each person would eat 2 spring rolls.
In this case, you can divide the total number of spring rolls (40) by the number of spring rolls each person would eat (2) to find the number of people that can be served.
40 spring rolls / 2 spring rolls per person = 20 people
Therefore, 40 spring rolls can serve 20 people if each person eats 2 spring rolls.
If the portion size or the number of spring rolls each person eats is different, you can adjust the calculations accordingly.
