Okay, I think I have arrived at all the answer to the questions thrown my way. However, how do I explain what is happening “graphically”, where the services are charging same rate?
To explain what is happening graphically when the services are charging the same rate, you can create a simple line graph. Here's how you can do it:
1. Choose the relevant variables: Identify the variables that you want to compare. In this case, since you are comparing service charges, you need two variables: the services being compared and the corresponding rates.
2. Select a scale: Determine the scale for your graph. Assign the x-axis (horizontal) to the services being compared and the y-axis (vertical) to the rates. Ensure that the scale allows you to clearly display the data points.
3. Plot the points: For each service, plot a data point on the graph. The x-coordinate represents the service, and the y-coordinate represents the rate. Since all the services are charging the same rate, the data points should be at the same height on the y-axis.
4. Connect the points: Since the rates are the same for all the services, you can connect the data points using a straight line. This line will be horizontal since the y-coordinate (rate) remains constant.
5. Label your graph: Add labels to the x-axis and y-axis to indicate the variables being represented. Provide a title for your graph to concisely explain what it represents.
By following these steps, you can create a graphical representation that demonstrates how the services are charging the same rate.
