The answer is: 59%.

Step-by-step explanation:

To calculate the percentage of people who have seen the movie we start from: y = - 0.414x + 106.55; and of x = 115; making the appropriate substitutions we would have left: y = - 0.414 (115) + 106.55; y = - 47.61 + 106.55; y = 58.94, which rounded to exceed 0.5 would be 59%.

The answer is: 59%.
