Answer:
The equation is ![A(d) = 80 - 4d](https://tex.z-dn.net/?f=A%28d%29%20%3D%2080%20-%204d)
Step-by-step explanation:
Linear function:
A linear function for the amount of money in an account after t days is given by:
![A(d) = A(0) - md](https://tex.z-dn.net/?f=A%28d%29%20%3D%20A%280%29%20-%20md)
In which A(0) is the initial value and m is the daily cost.
Your EZ Pass account begins with $80. It costs you $4/day.
This means that ![A(0) = 80, m = 4](https://tex.z-dn.net/?f=A%280%29%20%3D%2080%2C%20m%20%3D%204)
So
![A(d) = A(0) - md](https://tex.z-dn.net/?f=A%28d%29%20%3D%20A%280%29%20-%20md)
![A(d) = 80 - 4d](https://tex.z-dn.net/?f=A%28d%29%20%3D%2080%20-%204d)
