8. The menu of my favorite burger restaurant is written on a board. However, the rain washed away some of the numbers. The burgers are in order by price. Which of the following  is the price of one of my burgers? Feel free to pause to try and solve it. Okay, so the thing that we need to remember here is that these are written in ascending  order. So the price each time is getting bigger. Which means that the price of this burger over here, if we try to figure out what can be over here, it can't be a three, right?  Because then it would be smaller, or the price would be less than the price of this burger here, the veggie burger. So the classic burger has to be more expensive. So the smallest  number it can be is four, right? 430. And it could be five or 530 or 630. But let's try 430. First, because it's the smallest. So then if we look at the hot bacon, well,  the smallest it can be is 460. Right? Then next, the cheesy burger. Well, if the cheesy burger was 450, it would be less than the hot bacon burger, which is 460. That's not  allowed. So this one has to be bigger, it has to be 550. Right? And then lastly, we look at the double burger. And we can see that it can't be 510, right? Can't be 710.  It has to be 610. That's the only number that ends in a 10 over here. That's in between these two. So now we can see, try to answer the question of which one of these is the  price of one of the burgers. And we can see that option B over here is the price of the cheesy burger, right? Option B is 550. And the cheesy burger is also 550. So that's the  answer. The answer to number eight is option B.
