Felix is chopping down trees in his backyard. For every 13 trees he chops down he needs to get his axe resharpened. It cost him $5 to sharpen his axe. If he spends $35 on axe sharpening, at least how many trees has he chopped down? Let's think step by step and output the final answer after "####".

He has sharpened in 7 times because 35 / 5 = <<35/5=7>>7
He has chopped down 91 trees because 7 x 13 = <<7*13=91>>91
#### 91
