Question 1012265
The cost C is variable, it changes with the change in V, the number of videos you rented. The constant is 2, this is the cost per video regardless of number of videos you rent. So you'd have
C= 2V
2= 2(1)
4= 2(2)
6= 2(3)
8= 2(4)
and so on, where your cost goes up by 2 for every additional video you rent.
