Answer:
80 movies must be streamed. 
Step-by-step explanation:
To find the average cost, you must divide the total cost by the number of movies watched. 
When you watch 1 movie, you pay the initial fee of $80 plus a $4 purchase of the film. 
The equation is shown as such:
average cost = (total cost)/(number of movies)
Your total cost can be represented as  , while the number of movies is represented as
, while the number of movies is represented as  .
.
You want the average to equal 5, so your equation is shown as follows:

simplifying this, we get

which can then be simplified to 

X = 80 movies.

Answer: it will take her 56.67 seconds or 0.945 minutes to race 2 laps
Step-by-step explanation:
It takes Ella 1 minute and 25 seconds to complete the cheep beach course.
We can express this time in seconds or minutes. Expressing it in seconds,
1 minute = 60 seconds
Therefore,
 1 minute and 25 seconds = 60 +25 = 85 seconds
If the course is 3 laps long, that means she completed 3 laps in 85 seconds. The time it will take her to race 2 laps would be 
(2 × 85)/3
= 56.67 seconds
Converting to minutes, it will be 
56.7/60 = 0.945 minutes
