Answer:
Explanation:
Let x be the number of tickets sold before the tournament.
The number of tickets sold on the day of the tournament is x - 150 (since 150 fewer tickets were purchased on the day of the tournament than before the tournament)
The total number of tickets sold is the sum of the number sold before the tournament and on the day of the tournament.
x + (x - 150) = 898
Combining like terms:
2x = 1048
To find the number of tickets sold on the day of the tournament, we need to divide by 2:
x = 1048/2
x = 524
Therefore, 524 tickets were sold before the tournament and x - 150 = 524 - 150 = 374 tickets were sold on the day of the tournament.
