Answer:
Upper level = 2502 seats
Middle level = 5044 seats
Lower level = 7456 seats
Step-by-step explanation: given that
A baseball stadium holds 15,002 seats.
Let the Upper, middle and lower levels be represented as U, M and L respectively. And x = number of seat at the upper level
The lower level has 50 fewer than three times as many seats as the upper. That is
L = 3x - 50 .... (1)
The middle level has 40 more than twice as many seats as the upper level. That is
M = 2x + 40
Where L = x
x+ (2x + 40) + (3x - 50) = 15,002
You solved for x and found out the upper level has 2,502 seats . How many seats are in the lower level and how many seats are in the middle ?
That is x = 2502
Substitute x into equation 1
L = 3(2502) - 50
L = 7456 seats
Substitutes x into equation 2
M = 2(2502) + 40
M = 5044 seats
