a racetrack charges $80 each seat in the lower section, $65 for each seat in the upper sections, and $30 for field tickets. there are three times the number of seats in the upper section as compare to the lower section. the revenue from selling all 21,200 seats is $915,000. how many of each ticket were sold at the racetrack?

Each seat in the lower section costs $80, each seat in the upper section costs $60, and field tickets cost $40.
The upper section has three times the number of seats as the lower section.
The total revenue from the sale of all 24,200 tickets is $1,140,000.

The steps below can be used to calculate the total number of seats in each section:

Step 1 - In the lower section, enter 'x' as the total number of seats.

So, based on the data provided, the total number of seats in the upper field is '3x'.
Let y be the total number of seats in the field.

Step 2 - The linear equation that represents total ticket revenue.

80x + 60(3x) + 40y = 1140000
260x + 40y = 1140000 ...(1)

Step 3 - The linear equation representing the total number of tickets is as follows:

x + 3x + y = 24200
y = 24200 - 4x ...(2)

Step 4: Change the value of y in the equation (1).

260x + 40(24200 - 4x) = 1140000
x = 1720 tickets

Step 5: Change the value of 'x' in equation (2).

y = 24200 - 4(1720)
y = 17320 tickets

Therefore, the number of each ticket sold was:

The upper section contains 5160 seats, the lower section contains 1720 seats, and the field contains 17320 seats.
