A call center manager estimated that it costs on average 1.57 to set up a phone order (to greet a customer, record an address and credit card information, etc.). It costs an additional 0.86 for every item ordered. The manager is trying to understand the cost savings from convincing customers to order more items less frequently. What are the total savings from convincing customers to order five items in one phone call rather than in five separate calls?

Calculate total savings for all five items (not average savings per item). Enter your answer as a number rounded to two decimal points, e.g., 3.14, 25.70, 100.00, 1540.99. Do not enter any letters, unit symbols (such as %), commas, or other non-numerical characters!
