Consider a $4-$day task with a total planned budget of $$100.$ The task is scheduled to begin on a Monday, and the status date is set for the following Wednesday at noon. By this point in the timeline $($mid$-$Wednesday$).$ On the first two days of the task, a total cost of $$40$ per day was incurred. However, despite these expenditures, only $55\%$ of the work has been completed by the status date, as confirmed by progress reports. Given this percentage of completion, the task should have ideally incurred a cost of $55\%$ of the total budget, or $$55.$
