First, we subtract the 20 sign-up points from the number of points Nora needs to get a free movie ticket: 155 points - 20 points = <<155-20=135>>135 points.
Then, we divide the remaining number of points she needs by the number of points she earns per visit to find the number of visits she needs to make: 135 points / 12.5 points/visit = <<135/12.5=10.8>>10.8 visits.
Since Nora can't make a fraction of a visit, she needs to make at least 11 visits to earn a free movie ticket. Answer: \boxed{11}.
Nora has a points card for a movie theater.
She receives 20 rewards points just for signing up.
She earns 12.5 points for each visit to the movie theater.
She needs at least 155 points for a free movie ticket.
What is the least number of visits she needs to make in order to earn a free movie ticket?
