Answer:
I know the answer to question 2:
Each ticket cost $2.50.
Explanation:
He spent 36 dollars in all.
Take away $13.50 dollars since he needed that to get in the fair.
He had $22.5 left that he spent.
And there are 9 tickets that he bought.
22.5 divided by 9 is 2.5.
Therefore, each ticket cost $2.5.
I hope this helps, good luck.
