Answer 4

Well, let's think about this logically. If I have a certain amount of money, and then I spend parts of that money each day equally, we know that we're going to have less and less money after each day! That means that over time, the money I have in my car decreases hence the representative graph will decrease.

I initially have $6, and then each day, I'm losing $1.25 per toll that I cross each day! So if we let x represent the number of tolls, what do you think our equation will be?

Answer 5

I think it's D.

Answer 6

And why's that?
