Nathan needs to make 13 visits to make enough points for a movie ticket.
When Nathan joined, he received 40 reward points. This means that out of the 225 points he needs for a movie ticket, he now only needs:
= 225 - 40
= 185 points
He gets 14.5 points for every visit which means that the number of visits he needs to get to 185 points is:
= Number of points remaining / Number of points per visit
= 185 / 14.5
= 12.76 visits
= 13 visits
Nathan therefore needs at least 13 visits to get enough points.
