Hi guys! I'm really struggling with this problem since my professor never covered it in class and my friends and I have no idea how to apply the content of the book to the problem. Would you guys be able to post a step-by-step? We'd really appreciate it! I've attached the problem below: It's from the book Managerial Accounting (10th edition), Chapter 6, Problem 25E Here's a link to the problem:

(Remember to express your month when 34,000 answer in terms of the real.) 4. Build a spreadsheet: Construct an Excel spreadsheet to solve all of the preceding requirements. Show how the solution will change if the following information changes: in March there were 32,000 miles traveled and the cost was 20,000 real
