Please Write out all steps, calculations , Units so I can figure this out this out because I am very confused in class.

The assignment must be completed in groups of two. You are not allowed to submit your assignment individually. You must hand-write your answers and submit a scanned version(scanning/taking pictures with phone is ok) to Canvas. You must combine those several pages of scans/pictures into one Word or PDF file only. The assignment should be submitted to Canvas by one of the group members only (write the names of both team members on the assignment). Only PDF or Word format submissions are accepted. Do not submit the scans/pictures separately; combine them into ONE Word or PDF file, or your assignment will not be graded. Handwriting on iPad, Surface, etc. is accepted, but typing is not allowed. You are responsible for making sure the hand-writing is neat to read and the scanned copy/picture is of high-quality. No late assignments will be accepted for any reasons, and zero grade will be assigned. I encourage you to study the course material before attempting to solve the questions to reduce the chance of confusion, and to enhance your learning experience You will lose marks if you do not clearly mention the units, or do not clearly write down all steps of your calculations and solutions, at any part of the problems. It is your responsibility to follow this requirement in all parts of all questions. Question 1. Part I. A bakery uses a certain type of flour for their bagels at a rate of 30 bags per week. The bakery purchases each bag of flour for $7. The transportation cost and all other costs incurred by placing an order for bags of flour is $80 per order, and holding costs are based on a 10% annual interest rate. Assume each year is 50 weeks. (a) How many bags of flour should the bakery purchase at each order to minimize the total inventory costs? Compute the time between placing the orders based on this policy. (b) What are the annual holding and setup costs for this item under this policy? Part II. Suppose that even though the estimated demand was 30 per week, and optimal order quantity was obtained according to this information, it turns out that the actual demand is in fact 45 bags per week. (a) If we use the order size calculated in the previous problem, what will the setup plus holding cost be under the actual demand rate? (b) What would the cost be if we compute the new optimum order size based on the actual demand? (c) What excess cost was caused by that demand error
