Question

Laura rents a movie for a flat fee of $2.00 plus an additional $0.50 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Laura has the movie.
a. c(x) = 2.00x + 0.50
b.c(x) = 2.00 + 0.50x
c.c(x) = 2.50x
d.c(x) = (2.00 + 0.50)x

Answer 1

Hi.

The answer is:

b. c(x) = 2.00 + 0.50x

Cheers~

Answer 2

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
