Answer:
Yes.
I divided 22.5 by 3, and got 7.5
22.5/3=7.5
I then added 7.5 from 22.5
22.5+7.5,
and I got 30.
Once I got into the bigger numbers, I just multiplied 7.5 by the last number
7x7.5= 52.5
All the numbers were constantly added by 7.5, so
the table is a proportional relationship.
I hope this helped! +*♡
