For how many movies is the cost of the plans the same?

Question

Streaming plan charges an annual fee of $45 plus $2.50 per movie watched. Another plan has no annual fee but charges $3.75 per movie watched. For how many movies is the cost of the plans the same?

Answer 1

Let 'x' represent the number of movies watched so that the cost of the plans is the same:

45 + 2.50x = 3.75x
by solving we find:
x = 36 movies
