Use the table to answer the question. Number of cases ordered Number of rolls of paper towels 1 12 3 36 5 60 10 120 A restaurant is placing an order for paper towels. 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 appear? Write your answer as an ordered pair

1 answer

To find the constant of proportionality, we can divide the number of rolls of paper towels by the number of cases ordered.

Let's analyze the data provided in the table:

  • For 1 case: 12 rolls of paper towels → Ratio = 12 / 1 = 12
  • For 3 cases: 36 rolls of paper towels → Ratio = 36 / 3 = 12
  • For 5 cases: 60 rolls of paper towels → Ratio = 60 / 5 = 12
  • For 10 cases: 120 rolls of paper towels → Ratio = 120 / 10 = 12

In each case, the constant of proportionality is 12.

Thus, the ordered pair showing the constant of proportionality from the data table is (1, 12).
