Answer:
B) The equation <em>x </em><em>+ </em><em> (2 x + 40) + (3 x - 50) = 15,002 </em> 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 <em>x </em><em>+ </em><em> (2 x + 40) + (3 x - 50) = 15,002 </em> represents this scenario suitable.
