My solution is like the following:

I have an excel spreadsheet to work with
Customer: replied 1 month ago.
Company A
An electronic retail chain wishes to minimize its ordering costs for a particularly popular model of laptop computer. This retail chain has a line of credit to finance its inventory and the current interest rate is 1.5%. The chain estimates it can sell 30,000 units per year and it pays $575 per unit. It costs $48 to place each order. How many units should it order each time? You should round your answer up to the nearest laptop unit. You must show your work.
Company B
A manufacturer of laptop computers operates a plant with an annual capacity of 6,630,000 laptop units. One of its models is expected to sell 390,000 units in the coming year. How large should each product lot be if it costs $575 to change production from one model to another. Assume that the manufacturer values each laptop unit at $280 and it has a holding interest rate of 2%. You should round your answer up to the nearest laptop unit. You must show your work.


I'm sorry about the delay in replying, I had some computer issues that prevented me from getting your message.

You mentioned that you have an Excel spreadsheet for this. Can you attach a copy of that spreadsheet so I can see the format that you are supposed to follow?

Notes...To work part B step by step to get the order of operations right rather than trying to work it all at once find:
• D/P (if both given in same time frame - annual, etc)
• 1-D/P
• Ch (from rate * unit price)
• Denominator which would be Ch*(1-D/P)
• Numerator which would be 2*D*Cs
• Numerator/Denominator
• Sqrt(Numerator/Denominator)
• Roundup(Sqrt(Numerator/Denominator))

Hi again,

Please see the attached Excel file for the worked out solution:


You can copy and paste the information from this Excel file into the provided template.

Please feel free to ask if you have any additional questions about these solutions.

Hello Ryan,Thank you for your response . I apologize for the delay. I still need to show work , outlining how I arrive to the calculations.

Ok, I'll see what I can add to it. Excel is kind of a horrible platform for "showing work", but I'll do what I can.

Customer: replied 1 month ago.
Okay.thanks! You can type out your steps in the cells or you can use a word document and attach or take a screen image and put in the file.
Customer: replied 1 month ago.
There are 2 other parts to this course. Would you like me to send separately or attach as a document?

How about if I send a Word document that shows the work then?

Hi again,

Please take a look at the Word document at the following link and let me know if that meets your needs for this project.


Regarding the other parts for your course, you should post those in a new question since they are a separate assignment. If I was unable to help with those for any reason, having them posted here in this thread would make it more difficult for you to get help from another expert.

If there is anything else that I can do to help, please don't hesitate to ask.



Customer: replied 1 month ago.
okay..thank you so much!

You're quite welcome.

I looked at the other assignment. Yes, I can help you with that one.

Please be sure to rate the service that you received for the original task, and open a new question page for this new task. When you open the new page, be sure to put "For Ryan Only" at the beginning so that your request will be clear. Feel free to ignore responses from anybody who fails to honor your request, if you so choose.

Hi again,

Try this version:




Customer: replied 1 month ago.
I will. The excel has a 75% match as well.

Not sure we can do much about that. You were given fairly direct instructions about breaking down the calculation into steps. I would expect that pretty much the entire class will have similar looking Excel sheets.

Customer: replied 1 month ago.
Okay. Just want to make sure. I submitted a work solution before in excel for this same class and they rejected it due to matching similarities.
Customer: replied 1 month ago.
Did you get the file for the other solutions. I submitted a request on Sunday for that portion

You might change the wording of some of the labels for the quantities in the Excel sheet.

No, I didn't receive any files for that. How did you send them?

Ok, got it. I'll post the response in the other thread.
