Acar dealership has 240 cars in the parking lot and 17.5% of them are red. of the other 6 colors in the lot, each color has the same number of cars. if one of the color is black .how many blacks cars are in the lot?

First you have to find the amount of cars that aren't red by multiplying 240 by .175 which is 42 so then you subtract 240 by 42 and get 198. Then in order to find the a amount of black cars you will divide 198 by 6 and get 33 black cars.
