A restaurant is placing an order for paper towels. The data table shows the amount of paper towels rolls compared to the number of cases. At which ratio in the data table does the constant proportionality appear?

Without having the data table provided in the question, it is not possible to determine at which ratio the constant proportionality appears. Please provide the data table in order to answer the question accurately.

To determine the ratio at which the constant proportionality appears in the data table, we need more information. Please provide the data table or specific values for the amount of paper towel rolls compared to the number of cases.

To identify the ratio at which the constant proportionality appears in the data table comparing the number of paper towel rolls to the number of cases, we need to analyze the data closely.

Firstly, look for a relationship between the number of rolls and the number of cases. Calculate the ratio of rolls to cases for each row in the data table. The constant proportionality will be seen as a consistent ratio across all rows.

For example, if the data table looks like this:

Number of Rolls | Number of Cases
----------------|----------------
2 | 1
4 | 2
6 | 3
8 | 4

To calculate the ratio, divide the number of rolls by the number of cases:

2/1 = 2
4/2 = 2
6/3 = 2
8/4 = 2

In this scenario, the constant proportionality appears as a ratio of 2:1, which means for every 2 rolls, there is 1 case.

By analyzing the ratios for each row in the data table, you can identify the ratio where the constant proportionality appears.
