A movie complex is showing the same movie and three theaters in theater and a 60 of the 80 seats are taken and theater B 42 seat
Anna [14]

Answer:

Theatre C.

Step-by-step explanation:

Theatre A:

60 of the 80 seats are taken.

% seats taken = seats taken/total seats * 100

= 60/80 * 100

= 75%

Theatre B:

Total seats = number of seats taken + number of empty seats

= 42 + 18

= 60

% seats taken = seats taken/total seats * 100

= 42/60 * 100

= 70%

Theatre C:

Total seats = number of seats taken + number of empty seats

90 = X + 18

X = 72

% seats taken = seats taken/total seats * 100

= 72/90 * 100

= 80%

Theatre C with 80% of seats taken.
