If 30% of the cars in a lot are black, how many cars in total are black?

To determine how many cars in total are black given that 30% of the cars in a lot are black, we need to know the total number of cars in that lot. The choices provided may represent various scenarios, but without additional context about the total number of cars, it's impossible to pinpoint the exact quantity of black cars.

If we assume that the total number of cars is something that can be calculated from the given number of black cars, we would use the percentage to find the total. For instance, if there are 66 black cars, to find out the total number of cars, we can set up the equation based on the percentage:

Let the total number of cars be 'x'. According to the information:

30% of x = 66

0.3x = 66

x = 66 / 0.3

x = 220 cars

In this case, if 30% of the total cars in the lot equals 66, then the option provided aligns logically. It shows a direct relationship between the percentage of cars and the number of black cars. Hence, if you know there are 66 black cars, it reflects the calculation based on the provided percentage of 30%.

This reasoning helps illustrate why
