The constant of proportionality appears when the number of cases ordered is multiplied by a certain value to get the corresponding number of rolls of paper towels. In this case, the value is 12, because multiplying the number of cases by 12 gives the number of rolls of paper towels.
So the ratio where the constant of proportionality appears is (1,12).
Use the table to answer the question.
