Best Answer
To create a step graph to represent the data in the table, we first need to plot the points on a coordinate plane. We will place the time values on the horizontal axis and the cost values on the vertical axis.
For each row in the table, we will plot a point at the left endpoint of the time interval with a y-coordinate equal to the cost. Then, we will draw a horizontal line to the right endpoint of the time interval and plot a point at that location with the same cost value. This will create a step-like pattern.
Here is the step graph representing the parking fees:
Step Graph

Note that the step graph starts at (0, 0) because there is no cost for parking before 6:00 am. The graph ends at (12, 33) because the car park is open from 6:00 am to 6:00 pm, which is 12 hours.
