Sagot :
Answer:
1700 miles
Step-by-step explanation:
Solving the Problem
Setting Up the Equation
The agency charges $40 (per week) plus $0.10 for every mile driven. Since the time frame of the question is one week, we can consider 40 as a constant value.
The equation modeled by this problem is
y = 0.10x + 40,
where y is the total money charged after x miles.

Solving for X
We're told that after a week's use of a car how many miles must've been driven to be charged $210. We can plug this into the equation to find x.
210 = 0.10x + 40
170 = 0.10x
1700 = x
So, after 1700 miles driven, the agency charges $210.
