First, please do not use all capitals. Online it is like SHOUTING. Not only is it rude, but it is harder to understand. Thank you.
Isn't total sales indicated in in the statement of the problem? Total sales = 23,000 as indicated in your first line.
However, to calculate:
7650 = .17x, where x = total sales.
Likewise, 3750 = .25x for 2door cars
Then 4door cars = .33x
Does this help?
