Answer:
Car A: Initial Charge = 20
Car B: Initial Charge = 30
Car A: Rate = 5
Car B: Rate = 0
At 2 miles, their charges will be the same
Step-by-step explanation:
Given
<u>Car A</u>

per mile
<u>Car B</u>

Solving (a): The initial charge
First, we get the linear equation that represents both car's charges.
Represent number of miles with m.
So, the charges is:
<u>Car A</u>
<u></u>
<u></u>


Set m to 0 to get the initial charge:


and

<u>Car B:</u>
i.e. Rate is 0


So:
and 
Solving (b): When their charge wil be equal.
To do this, we set:





<em>At 2 miles, their charges will be equal</em>
