Answer:
The total number of seats in the arena is 45000.
Step-by-step explanation:
Let the total number of seats in the arena be x.
It is given that 62% of the tickets are sold. it means 38% seats are still available.
A total of 17,100 seats are still available for the next hockey game.
Multiply both sides by 100.
Divide both sides by 38.
The value of x is 45000. Therefore the total number of seats in the arena is 45000.
