The table below shows the total cost of bottled water based on the number of cases you bur
Part A
Number of Cases Total Cost (5)
Do these data show a proportional relationship? Explain your answer
Use the drop-down menus to complete the statements
10
To decide if data in the table are in a proportional relationship, you need to choose
of the total cost to the number of cases
45
The data are in a proportional relationship it Choose
In this case, the data Choose in a proportional relationship and the constant of proportionality Choose
Part B
Which statements are true?
Select all that are correct
The points (0,0) and (1,5) are on the graph representing the data in the table
The unit rate of number of cases per dollar is
If this is a proportional relationship, 25 cases will cost $120.
One way to show whether this is a proportional relationship is to graph the data and see if the result is a straight line that does not go through the
origin
The unit rate does not equal the constant of proportionality, so the data are not in a proportional relationship
