Do not worry too much!

1. one dozen = 12 cars
2. 12 cars each (= each of 12 cars) weighs 2 tons. So total = 12*2=24 tons
3. total tons and kilometers = 24*n
4. one ton and one kilometers costs x dollars, so total costs : x*24*n dollars

So E

x dollars per ton, and for one dozen cars @ 2 tons each is 24 tons, and then we have n kilometres.
