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
.
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.
