To determine the variables in the given graph and describe their relation at various points.
Answer to Problem 5PPE
Total cost & Number of pounds, they are related linearly.
Explanation of Solution
Given: A graph is given as follows.
As, one can see in the graph, there is change in the total cost with the change in number of pounds. So, the two variables in the given graph is ‘Total cost’ and ‘Number of pounds’.
The two variables are related linearly but in two parts having two different slopes. The first which starts from origin is having a higher slope but after a certain point the slope reduces suddenly and that causes less change in total cost with the change in number of pounds as compared to the part with higher slope.
