There were 472 runners altogether in the marathon. 185 have already crossed the finish line. How many are yet to complete the race?

There are 287 runners left to complete the race. I Choose to do this one since I got very very confused doing the other ones such as he sold half of his eggs 3 times while not stopping to get more. 

472-100=372

372-85

372-72=300

85-72=13

300-13=287
