The constant of proportionality can be found by calculating the ratio of the number of rolls to the number of cases.

For the first ratio, 12 rolls / 1 case = 12.
For the second ratio, 36 rolls / 3 cases = 12.
For the third ratio, 60 rolls / 5 cases = 12.
For the fourth ratio, 120 rolls / 10 cases = 12.

Therefore, the constant of proportionality appears at the ratio (12,12).
