The initial value in a graph represents the y-intercept, which is the cost when the number of hours is zero. Based on your description, if the y-intercept (the cost when no hours have been spent diving) is indicated on the graph, that value would correspond to the fixed equipment rental fee.
To select the correct answer, look at what the y-intercept is from the graph you have. If you can identify the point where the line crosses the y-axis, that will provide the initial cost.
If you don't have the graph but it shows a starting cost that corresponds to one of the answer choices, pick that value.
If the graph has not been provided and requires interpretation based on a typical scenario where there are fixed costs to start, it could likely be one of the given options.
If you'd like to provide more context or details about what the graph looks like, I could help you determine the initial value more precisely!
