I would start with checking the number of population in US = 330 million (approx)
Each household = 2.5 members (approx)
Population each household = 132 million (approx)
Car ownership each household = 1.5 cars (approx)
Total no. of cars = 132 * 1.5 = 198
No of cars a typical gas station can service = 2500 cars
No.of gas stations = 198 million / 2500
