I feel like a lot of the puzzles in Professor Layton games are like this. Any time you find yourself starting some complex algebra or multiplication, you need to consider rereading the problem and seeing if you just need to pick a number that’s there.
For example: A bus can travel 100 miles on a full tank with its full passenger load of 80 people. If everyone gets off the bus, then how far can it travel?
The answer
0 miles. With everyone off, there’s no one to drive it.
I think this is supposed to be a trick question.
Based on my kids math questions… I’m not so sure…
