Half of the 400 vehicles for sale on the lot are Dodges, or a total of 400/2=<<400/2=200>>200 Dodge vehicles.
Since there are half as many Hyundai vehicles on the lot as there are Dodge vehicles, then there are 200/2=<<200/2=100>>100 Hyundai vehicles on the lot.
Since the remainder of the vehicles are Kias, then there are 400-200-100=<<400-200-100=100>>100 Kia vehicles for sale on the lot.
