Firm B faces the following:

Revenue per order = $8000

750 orders/deliveries per year

Net cost as a percent of revenue = 60%

80% of late deliveries redelivered; 20% cancelled

Cost of redelivery = $350

Invoice deduction for redeliveries = $250

4. What is the total lost profit or cash flow from an 85% on-time delivery rate?

5. What is the total lost profit or cash flow from a 95% on-time delivery rate?

6. What is the percentage reduction in total lost profit or cash flow from this 10% increase in on-time delivery?

Please solve this question steps by steps. Do not use Excel spreadsheet. It is really important for me. Thank you very much.
