Answer:
[tex]150\ tickets[/tex]
Step-by-step explanation:
Let
t -----> the number of tickets
y ----> the total amount raised
we know that
The linear equations that represent this situation are
One Class
[tex]y=3.50t+450[/tex] -----> equation A
Other Class
[tex]y=4.00t+375[/tex] -----> equation B
Solve the system of equations
Equate equation A and equation B and solve for t
[tex]4.00t+375=3.50t+450[/tex]
[tex]4.00t-3.50t=450-375[/tex]
[tex]0.50t=75[/tex]
[tex]t=150\ tickets[/tex]
