Question

A recipe calls for 1 cup of cake mix and 4 eggs. This recipe serves 6 people. How many eggs are needed to make enough to serve 15 people?

Answer 1

10eggs (if you can make 'half' a cake, otherwise 12)

Explanation:

We need to know how many cake mixes are needed. If we know one mix is for 6 people then;

`15/6=2.5` mixes for 15 people

Therefore, we need 2.5 times the eggs to make enough cake for 6 people (4 eggs).

`4*2.5=10` eggs

If the cakes needed to be whole, however, then we need to round up the 2.5 to 3, and thus;

`4*3=12` eggs
