To solve this, you need to get the slope of both tables.
Use the following formula:

Public Table:
Use the points (2, 24) and (5, 60)

Wholesales Table:
Use the points (18,162) and (35, 315)

Once you find the slopes of both tables, you need to compare the two numbers
For instance, 2 is what of 6? It is 2 /6 of 6
