Answer:

C) 6

Explanation:

From the given data we can find the constant of proportionality by dividing The number of people by number of cars.

Constant of proportionality =
\frac{\textrm{Number of people}}{\textrm{Number of cars}}

Taking any point from the table will give the same constant of proportionality as they are proportional quantities.

Constant of proportionality =
(18)/(3)=(30)/(5)=(36)/(6)=(48)/(8)=6

This can be written as 6 people per car.

For 10 cars, number of people will be =
10* 6=60 people.
