Assuming no safety stock, what is the re-order point (R) given an average daily demand of 50 units, a lead time of 10 days and 625 units on hand?

Thanks to invite...!!

Place the order when you have left units in hand.

I agree with the answer of Mr. Awad.

I also agree with Mr. Nadeem Asghar's point of views to be considered at the time of re-ordering. 

I agree to both of above replies and would like to add the following as well from a reply given by Mostafa Abouelsaad to a very similar question earlier:  

Quote:

However you should also consider the following factors before ordering:

• Is there a minimum order quantity for the needed units?
• Is it a seasonal product?
• Is your Purchasing budget enough for the needed units?

Agreed with Awad  reply ------------

You need to multiply 50 X 10 and take out the 625 unit so you will get it.
