Answer:
D) Â Total number of seats in the theater is 300.
Step-by-step explanation:
Total income of the movie theater  = $3,600
The cost of VIP tickets = $20 per person
The cost of regular tickets  = $8 per person
Let the number of VIP tickets sold = Â m
So, the total number of regular tickets sold  = 2m
Now, Earnings from selling VIP tickets
= Number of VIP tickets sold  x Cost of each VIP ticket
=  m  x $20 = 20 m
Also, Â Earnings from selling regular tickets
= Number of regular tickets sold  x Cost of each regular ticket
=  2m  x $8 = 16 m
Total Earnings  = Earning from VIP tickets + Earning from Regular tickets
             = 20 m  + 16 m  = 36 m
or,  36 m  = $3,600
⇒ m  = 3600/36 = 100
Hence, the number of VIP tickets sold  = m = 100
and Regular tickets sold  = 2 m = 2 x 100 = 200
Now, the total number of seats in the theater
 =  VIP tickets + Regular tickets
= Â 200 + 100 Â = 300.
Total number of seats in the theater is 300.
