There are 21 white cars in the parking lot. These cars represent 35% of all the cars in the parking lot.

How many cars are in the parking lot?

your all wrong. it is 60 cars.

To find out how many cars are in the parking lot, we can use the concept of proportions.

Let's assume that the total number of cars in the parking lot is represented by "x".

We are given that the 21 white cars represent 35% of all the cars.

This can be expressed as:

21 = 0.35x

To find the value of "x", we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.35:

21/0.35 = x

Simplifying the left side of the equation, we get:

60 = x

Therefore, there are 60 cars in the parking lot.

0.35x = 21

it is 21
