Andy, Mary, Leta, and Paul have eight days to collect money for a walk-a-thon to support their school. In the given graph, they have each recorded the relationship between the number of days and the amount of money collected.

Question

Whose collection shows a proportional relationship between the amount of money collected and the number of days?
A.
Leta's collection
B.
Paul's collection
C.
Mary's collection
D.
Andy's collection

Answer 1

To determine whose collection shows a proportional relationship between the amount of money collected and the number of days, we need to look at the relationships in the given graph.

A proportional relationship means that as the number of days increases, the amount of money collected increases at a constant rate. This can usually be identified by checking if the relationship forms a straight line that goes through the origin (0,0). In other words, for every unit increase in days, the amount collected should increase by a constant amount.

Unfortunately, as I can't see the graph you're referring to, I can't provide a definitive answer. However, you should look for the following criteria:

1. A straight line on the graph.
2. The line should pass through the origin (0,0).
3. The slope (rate of change) should be constant.

You can use these criteria to analyze each person's collection on the graph and determine who has a proportional relationship.
