Enrique Hooper · Answer 1

B. c (x) = 2.00+0.50x

It should be 2.00 because there won’t be any variable affecting it. It’s just a flat fee. 0.50x is right because the answer will vary according to the number of nights Laura has the movie and x represents how many nights she has the movie.

Hope this
