Determine the average processing time for applications, the average days tardy for each customer's application, and the average number of applications being processed if the bank processes the applications in the order they were received. (Round your answers to 2 decimal places.) Answer is complete and correct. Average flow time Average tardiness ...-------------... 32.33 days 16.33 days c.

Now assume the bank accounces that it will take into account both the processing time and the due dates in order to determine the order of the applications to be processed (CR). Calculate the average processing time, average tardiness, and average number of applications. (Round your answers to 2 decimal places.) * Answer complete but not entirely correct. Average flow time Average tardiness Average number of jobs 31.67 days 15.50 days 3.31 applications
