The correct option will be: A. 67%

Step-by-step explanation

Given equation is:
y = -0.414x + 106.55 , where
x is the length of the film in minutes and
y is the percentage of people finish watching the film.

Here, the length of the documentary is given as 95 minutes. So, we will plug
x=95 into the above equation
and get....


y=-0.414(95)+106.55\\ \\ y=-39.33+106.55\\ \\ y=67.22 \approx 67

(Rounded to the nearest percent)

So, the percentage of people in an audience who will finish watching a documentary that is 95 minutes long will be 67%
