Answer: $1200 was made from selling the $6 ticket.
Step-by-step explanation:
Let x represent the number of tickets sold at $6 per ticket.
Let x represent the number of tickets sold at $11 per ticket.
A total of 450 tickets were sold. It means that
x + y = 450
The total amount for which the tickets were sold was $3,950. It means that
6x + 11y = 3950- - - - - - - -- - - 1
Substituting x = 450 - y into equation 1, it becomes
6(450 - y) + 11y = 3950
2700 - 6y + 11y = 3950
- 6y + 11y = 3950 - 2700
5y = 1250
5y = 1250/5
y = 250
x = 450 - y = 450 - 250
x = 200
The total amount made from selling the $6 tickets is
200 × 6 = $1200
