Abaseball stadium holds 15,002 seats. the lower level has 50 fewer than three times as many seats as the upper
level. the middle level has 40 more than twice as many seats as the upper level. let x represent the number of
upper-level seats
which equation represents this scenario?
x + (2x + 20) + (3x – 50) = 15,002
x+ (2x + 40) + (3x – 50) = 15,002
x + 2(20 + x) + 3(50 – x) = 15,002
x + 2(x + 20) + 3(x - 50) = 15,002

B) The equation x + (2 x + 40)  + (3 x - 50)   =  15,002 represents this scenario suitable.

Step-by-step explanation:

Let x represent the number of  upper-level seats.

Total seats in stadium = 15,002

Now, seats in the lower level =  3 ( Seats in upper level ) - 50

= 3x - 50

or, the total seats in the lower level = (3 x - 50)

Also,  seats in the middle level =  2 ( Seats in upper level ) + 40

= 2x + 40

or, the total seats in the middle level = (2 x + 40)

Now, according to question

Upper Level seats + Middle level seats + Lower level  = Total seats

⇒ (x) +  (2 x + 40)  + (3 x - 50)   =  15,002 seats

Hence, the equation x + (2 x + 40)  + (3 x - 50)   =  15,002 represents this scenario suitable.
