Mathematics
1 answer:
vivado [14]3 years ago
7 0

Answer:

The equation is A(d) = 80 - 4d

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

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

So

A(d) = A(0) - md

A(d) = 80 - 4d
