Question

In a small U.S. city, the ratio of people to cars is approximately 1.85 : 1. If 12,100 people live in
the city, to the nearest 100 cars, approximately how many cars are in the city?

Answer 1

Answer:

$6,500\ cars$

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

$\frac{x}{y}=\frac{1.85}{1}$

$x=1.85y$ -----> equation A

12,100 people live in  the city

so

$x=12,100$

substitute the value of x in the equation A

$12,100=1.85y$

solve for y

$y=6,540.54\ cars$

to the nearest 100 car

$y=6,500\ cars$
