Answer:
The algorithm is as follows:
1. Start
2. bottles = 0
3. While bottles != 500
3.1 Create bottle
3.2 bottle = bottle + 1
4. Switch off machine
5. Stop
See attachment for flowchart
Explanation:
This begins the algorithm
1. Start
This initializes bottles to 0
2. bottles = 0
The loop is repeated until 500 bottles is created
3. While bottles != 500
This creates a new bottle
3.1 Create bottle
This increments the number of bottles by 1
3.2 bottle = bottle + 1
This switches of the machine after all bottles are created
4. Switch off machine
End algorithm
5. Stop
