im getting D @jim_thompson5910

jimthompson5910 (jim_thompson5910):

why do you think that

OpenStudy (anonymous):

it makes no sense to me.

OpenStudy (anonymous):

it seems as if their would be no correlation

jimthompson5910 (jim_thompson5910):

so the time length of the film has nothing to do with how many you can fit them in a day?

OpenStudy (anonymous):

i would say C but i got that one wrong for some reason.

jimthompson5910 (jim_thompson5910):

basically, the shorter the movie, the more you can play it in a single day the longer the movie, the less you can play it in a single day

jimthompson5910 (jim_thompson5910):

so that's why D has correlation

OpenStudy (anonymous):

so were looking at A as our answer?

jimthompson5910 (jim_thompson5910):

if more people pay to see the film, will the film earn more money?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

oh wait lol its B, i see now.

jimthompson5910 (jim_thompson5910):

guess that's the only thing left
