Since the constant of proportionality is the factor by which the number of cases is multiplied to get the number of rolls, we need to find a ratio in the data table that remains constant. Looking at the data table:
(Number of Rolls) : (Number of Cases)
(6, 1)
(24, 4)
(18, 3)
(30, 5)
The ratio between the number of rolls and the number of cases is constant at 6:1 for all the data points. Therefore, the constant of proportionality is paper is 6, and the ordered pair is (6, 1).
A restaurant is placing an order for paper towel. The data table shows the amount of paper towel rolls compared to the number of cases. At which ratio in the data table does the constant of proportionality paper?
