The complete Question is:

The formula is m=4a+2c , where c = number of children; m = number of meatballs; a = number of adults.

How many meatballs are required for a party of 20 adults and 5 children?

90

Step-by-step explanation:

The expression which gives the relation between number of children, adults and meatballs is:

m = 4a + 2c

We have to find the number of meatballs for a party of 20 adults and 5 children.

In the above formula, a represents the number of adults. So, this means we have been given a = 20

c represents the number of children. So this means c = 5

Substituting the value of a and c in the above formula, we get:

m = 4(20) + 2(5)

m = 80 + 10

m = 90

Thus, 90 meatballs are required for a party of 20 adults and 5 children.
