Wow, I was actually right!

Answer 7

Neil has 80% of Larry's # of cards.
Neil has 80 cards less than Larry

This means that the 80 cards is the 20% that he doesn't have.

If Neil has 80%, then,

80 x 4 = 320 cards

Neil has 320 cards.

80 x 5 = 400 cards

Larry has 400 cards.


Altogether, 720 cards.
