in a parking lot, 16% of the cars are blue. There are 4 blue cars in the parking lot. How many cars in the parking lot are NOT blue?
0.16x = 4
4 / 0.16 = 25 cars in the parking lot.
25 - 4 = ?
To determine the number of cars in the parking lot that are not blue, we need to find the total number of cars in the parking lot.
Let's use a variable "x" to represent the total number of cars in the parking lot.
Given that 16% of the cars are blue, we can set up the following equation:
0.16 * x = 4
To solve for x, we can divide both sides of the equation by 0.16:
x = 4 / 0.16
Dividing 4 by 0.16, we find:
x = 25
So, the total number of cars in the parking lot is 25.
To find the number of cars that are not blue, we can subtract the number of blue cars from the total number of cars:
Number of cars NOT blue = Total number of cars - Number of blue cars
= 25 - 4
= 21
Therefore, there are 21 cars in the parking lot that are not blue.
