Problem:
"A baker has a whole loaf of bread.

How many cuts must she make to have 9 slices?"
Your two hints:
"One cut will make two slices, two cuts will make three slices, and so on.

Therefore, we need 8 cuts to make 9 slices."

Now, what I mean by unclear is that in my opinion, it's 9 cuts to make 9 slices.
First cut: 1 slice, 1 almost whole loaf.
Second cut: 2 slices, 1 smaller loaf.
And so on, until you reach the 9th
Ninth cut: 9 slices, 1 stump of loaf left.
If the loaf had been exactly 9 slices in length, 8 cuts would have been correct. But I don't count a stump as a slice, do you? :-)
