Question

Help Please!!
Michelle rents a movie for a flat fee of $1.50 plus an additional $1.25 for each night she keeps the movie. Choose the cost function that represents this scenario if x equals the number of nights Michelle has the movie.
a .c(x) = 1.50 + 1.25x
b. c(x) = 1.50x + 1.25
c . c(x) = 2.75
d . c(x) = (1.50 + 1.25)x

Answer 1

f(x) = 1.25x + 1.5

Answer 2

Movie = $1.50.
Fee per extra night = $1.25x
x = Extra nights.
Cost = $1.50 + $1.25x

Answer 3

Okay. Well no matter what she'll be paying $1.50 since that's the flat fee. So it's $1.50 plus how much she's paying for whatever time she keeps it. If I'm paying 2 dollars a night and I'm keeping the movie for 3 nights, I would multiply 2 and 3 to find out I'm paying $6.

So if x is the amount of days she is keeping the movie, you're going to multiply that by the cost per night-$1.25.
So the answer is c(x)= 1.50 + 1.25x, your first choice.

Do you understand?
