Answer:
65 + 12.5v = m (M being free movie)
Explanation:
65 for the original 65 poitns he gets for signing up, then if he gets 12.5 points for every movie he visits then you need to multiply 12.5 times the amount of movies he went to (v) so it would be 65 + 12.5v
v would need to be 11.6
If you do 210 - 65 thats 145, then you do 145 divided by 12.5 which would get you 11.6
