Question

Nancy joined Movies Extraordinaire for a $8 fee and an agreement to pay $1.99 per movie she rents.  The equation for her total cost is y = 1.99x + 8.  Predict her total cost if she rents 25 movies.  Enter the numerical answer only.

anonymous · Answer

The x variable represents the amount of movies, and the y variable represents the total cost. So, to find the total cost, we need to plug in 25 for x:
$$y=(1.99)(25) + 8$$And evaluate.
