Answer:

[tex]6,500\ cars[/tex]

Step-by-step explanation:

Let

x ---> the number of people

y ---> the number of cars

we know that

The ratio of people to cars is approximately 1.85 : 1

so

[tex]\frac{x}{y}=\frac{1.85}{1}[/tex]

[tex]x=1.85y[/tex] -----> equation A

12,100 people live in  the city

so

[tex]x=12,100[/tex]

substitute the value of x in the equation A

[tex]12,100=1.85y[/tex]

solve for y

[tex]y=6,540.54\ cars[/tex]

to the nearest 100 car

[tex]y=6,500\ cars[/tex]
