Answer:
5
Step-by-step explanation:
We start by seeing how many families we have in total, which is 20. We then must subtract the number of families with girls only, the number of families with both boys and girls, and the number of families with no children. 20 - 7 is 13, then 13 - 8 is 5, and 5 - 0 is 5.
"Alia gets 4^2 fewer than Kelly, who gets 3^3."
So it's about a subtraction.

Hope this helps.
