How to solve Vending Machine Puzzle in Escape the Backrooms

At the end of the first section of the Abandoned Office level, you will come across a group of vending machines and a locked door in a room. Each vending machine has a number keypad (0-8). You must input the proper number on each of the four vending machines to open the locked door in the room.
The key to solving the puzzle is the picture that is plastered on the vending machine. Each of the four vending machines will have a separate picture of a Chair, a Table, a Water Cooler, and a book.
If you look around the room, you will find a certain number of books, tables, chairs, and a water cooler placed in the room. Just count the number of objects and input that specific number into their respective vending machine.

On our run, we encountered six chairs in the room, so adding the number six into the vending machine with a picture of a chair helped finish a portion of the puzzle. Do the same for all vending machines to open the locked door in the room.
There is no order or sequence to the puzzle; just input the right number into the vending machine and move on to the next one.
Remember that each Abandoned Office run will be different from the last; the game also follows an RNG system in its puzzles. So, each run, you will find different numbers of books, tables, chairs, and water coolers to make your next run fresh, but the solution to solving them stays the same, like the Colour Code Puzzle in Escape the Backrooms.
