Two adults and three children.
Budget: 13 adult tickets, or highlight_green%2813p%29 dollars is their budget.

p=2q, the last part of the description.


Family See Two Movies:
How much money unspent?
13p-2%2A2p-3%2A2q
13p-4p-6q
9p-6q
substitution
9p-6%28p%2F2%29
9p-3p
highlight%286p%29------how much is still unspent from original 13p budget.


This looks like they can see one more movie each; but I did not actually do the steps here for this last question.
