Question

Six out of the first ten vehicles that entered a parking lot were cars. Based on this information, if five hundred forty vehicles entered the parking lot, how many vehicles could be expected to be cars?

Answer 1

x = number of cars = 324

Explanation:

Total vehicles = 10

Cars = 6

Total vehicles : cars = 10 : 6

if five hundred forty vehicles entered the parking lot, how many vehicles could be expected to be cars?

Let

x = number of cars

Total vehicles : cars = 540 : x

Equate both ratios

10 : 6 = 540 : x

10/6 = 540/x

Cross product

10 * x = 6 * 540

10x = 3240

x = 3240/10

x = 324

x = number of cars = 324
