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?
Answer:
90
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.
