Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Jason bought a new bookcase that can hold a maximum of 80 pounds of weight. Jason has 70 hardcover books that each weigh half a pound, 30 textbooks that each weigh 2 pounds, and 3 knick-knacks that each weight 6 pounds. How many pounds over the bookcase's weight limit is this total collection of items?


### Response:
 Les 70 livres reliés pèsent 70 * 0,5 = <<70*0.5=35>>35 livres
Les 30 manuels scolaires pèsent 30 * 2 = <<30*2=60>>60 livres
Les 3 bibelots pèsent 3 * 6 = <<3*6=18>>18 livres
Le poids total est de 35 + 60 + 18 = <<35+60+18=113>>113 livres
La limite de poids de la bibliothèque est de 80 livres, donc le poids total de la collection de Jason est de 113 - 80 = <<113-80=33>>33 livres au-dessus de la limite de poids de la bibliothèque
