Question

The local high school hosted a hockey tournament. Tickets were sold before the tournament and at the door. When reviewing the ticket sales, the director of the tournament realized that there were 80 more tickets purchased before the tournament than at the door. A total of 820 tickets were sold. Which statements about ticket sales are true

Answer 1

380 tickets were sold at the door and 440 tickets were sold before

Explanation:

x = tickets sold before

y = tickets sold at the door

x + y = 820

x = y + 80

y + 80 + y = 820

-80 -80

2y = 740

y = 370

820 - 380 = 440

x = 440
