Sadie · Answer 1

Robyn model makes more sense and Marks is nonsense.

Step-by-step explanation:

In this question, calculations not required. All we have to do is consider each model logically.

Marks

Marks model shows 20 rather than 2 which means 200 is 10 times as much as 20. It does not make any sense.

Robyn

Robyn model shows 2 which means 200 is 100 times as much as 2 and this is not only correct but also makes sense because 100 * 2=200
