This problem deserves to be solved in one line: so simple it is.


     number of cars = %2832197-100%29%2F%280.09%2A15000%29 = 23.77  cars,   or 24 cars rounded.     ANSWER

Solved.


It is how our teachers taught us at my 4th - 5th grade, when we just knew percents, but still didn't know equations.

Their educational style was amazingly  PERFECT:  do not spend time writing equations, when and where it is not necessary;
use the knowledge you just have;  go straight ahead to get the answer in one line;  use the power of your mind.
Then check yourself.
