Answer: There are 33 black cars in the lot.
Step-by-step explanation:
Given : A car dealership has 240 cars in the parking lot and 17.5 percent of them are red.
i.e. Total cars = 240
Percentage of red cars = 17.5 %
Number of red cars = 17.5% of 240
[tex]0.175\times240=42[/tex]
Then , the number of cars of other colors = 240-42=198
Also, it is given that : Of the other 6 colors in the lot, each color has the same number of cars.
If one of the colors is black , then the number of black cars will be :-
[tex]\dfrac{198}{6}=33[/tex]
Therefore , there are 33 black cars in the lot.
