Answer:
66
Explanation:
The recipe states that a 4 egg cake mixture will serve 12 people.
To find the number of people a 1 egg cake mixture will serve: 12 ÷ 4 = 3 ⇒ 1 egg will make a cake big enough to serve 3 people.
If Gareth has 22 eggs, then 22 x 3 = 66
So a 22 egg mixture will be able to serve 66 people.
