Okay so we need four people.   We can either do 2 girls 2 boys, 3 girls 1 boy, or 4 girls.  These are mutually exclusive so if we can just add them up without double counting.

Do you still need further help?

4 boys and 8 gil? Hmm so you give 2 gil to each final fantasy character, and let them go shopping :O

Okay, another hint.  The action of choosing 2 boys and then 2 girls are both independent.  Thus we can count them individually and multiply them to count both.

Now I've made it really easy for you.
