Problem number 20, Dino moves from the entrance to the exit by going through rooms. You can only go through each room once. Dino adds up the numbers as he passes through each room.  What is the highest total Dino can make? 27, 29, 32, 34, or 36.  So the highest total would be for him to move through all the rooms.  So, as we see, Dino can not go through all of the rooms. So we have to drop the smallest one, but we cannot drop the room with the number one because  that is the only entrance, so we would have to drop the two. So let's see if he can go that way.  1, 5, 6, 7, 3, 4, 8, and he can go that way. So now we have to add up all these numbers, so 1 plus 5 plus 6 plus 7 plus 3 plus 4 plus  8 equals, to make it easier to count, we are going to make these things into tens. So we have 6 and 4 which is 10, 7 and 3 make 10, and then 10 plus 10 is 20, plus 8 is 28,  plus 5 is 33, and plus 1 is 34, which means our answer is D.
