The constant of proportionality appears when the ratio between the number of rolls of paper towels and the number of cases is the same for all data points. Looking at the table, we can see that the ratio is always 12 rolls of paper towels per case.

Therefore, the constant of proportionality appears at the ratio (12, 1).
