An arena has 49,000 seats that sell for $25 on the ground level, $20 on the mid-level, and $15 on the upper-level.
The number of seats on the upper-level equals the total number of seats on the ground
level and mid-level combined.
Suppose the arena brings in $882,500 from a sold-out event.
Ticket
a. Define variables to represent the number of seats in each level. (Hint: You need three variables)
b. Write a system of equations that models this situation. (Hint: Because you have three variables you need three
equations)
