You can put this solution on YOUR website!
Do this one backwards
After the last fence, he has 1 apple.
Before the fence he had x apples
You are told x%2F2+-+1%2F2+=+1
x%2F2+=+3%2F2
x+=+3 so he hads 3 apples before the last fence.
Now go back to fence 2
3+=+y%2F2+-+1%2F2
7%2F2+=+y%2F2
y+=+7 He had 7 apples before he hopped the second fence
Now all the way back to the fence closest to the tree
7+=+z%2F2+-+1%2F2
15%2F2+=+z%2F2
z+=+15
He started with 15 apples
He had to give 8 apples to the first farmer
4 apples to the second farmer
2 apples to the last farmer
and he ges one lousy apple for all his hard work and fence jumping
I hope it was worth it.
How about THEM apples :)
