Question

a video club costs $25 to join. each video that is rented costs $2.50. let v represent the number of videos. identify the independent and dependent variables. then, write a rule in function notation for the situation

Answer 1

2.5(v) + 25 because the 2.5 is the independent variable that never changes.

Answer 2

`C(v)=25+2.50v` - C(v) is the dependent variable and y in independent variable.

Explanation:

Given : A video club costs $25 to join. each video that is rented costs $2.50. let v represent the number of videos.

To find : Identify the independent and dependent variables. then, write a rule in function notation for the situation ?

Solution :

Let v represent the number of videos.

Each video that is rented costs $2.50.

So, v number of videos rented costs $2.50v.

A video club costs $25 to join.

The equation represent the situation is
`C(v)=25+2.50v`.

Here, C(v) is the dependent variable and y in independent variable.
