The minimum number of movies that she must watch to save money with the monthly subscription is x = 5.
How many movies should she watch to save money?
We know that each movie costs $2.95, so if you watch x movies, the cost is:
C(x) = x*$2.95
Then we must solve:
C(x) = $12.95 = x*$2.95
If we solve that for x, we get:
x = $12.95/$2.95 = 4.3
This means that if she watches 4.3 movies, then she gets more value for the monthly subscription.
To get only whole numbers we round up, we conclude that she must watch 5 or more movies per month.
So the solution is given by the inequality.
x ≥ 5
