Two mins to calculate.

No. Kids need to learn (and maybe be explicitly told) that a key to do well on tests like this is figuring out what the teacher wants. Clearly here you are not supposed to split it down the middle. The trick here is that it does not take 2x to do 10 cuts v 5, but 2x + 1.
But it's not 10 cuts, Einstein. It's 9 cuts for 10 pieces.

40.
Takes him 2x as long for 2x the amount.
