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.
