I do believe the answer is 52, sorry if i’m incorrect
No it does not stay the same
Original ratio is 6:5 which means it will only stay the same if the amount of movies to band is taken at multiples of this ratio. per sample if 24 movies are sold then
24/6=4 so you will have to multiply or sell 5*4=20 of the band ones to be able to keep same ratio.
That's what I did and since the zeros would be -5 and 3 the answer would be 3 since it can't be a negative
