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
