Mark's model is nonsense

Step-by-step explanation:

- Marks model shows 20 instead of 2.

- His model shows 200 is 10 times as much as 20. It does not make any sense.

- Robyn model shows 2 correctly, implicating 200 is 100 times as much as 2.

- Because,

                        2 * 100 = 200

So Mark's model is nonsense!
