Answer:
22 tickets
Step-by-step explanation:
I assume you're asking about question 2
To find a fraction of a whole number you divide by the bottom number and multiply by the top number. If 2/3 are kids tickets then 1/3 are adult tickets so you divide by 3 and multiply by 1

Youll have 80 pennies. dime=.10 10x8=80
To find the inverse of a relation, we switch the x and y values in each point.
So the inverse would be {(4, -3), (0, -1), (0, 6).
