Please solve the following two (2) problems "by hand" (no Excel or Words will be accepted) using pencil and eraser (or pen). Since some pencils write very lightly, please ensure your work is readable. Also, please make sure to solve the problem clearly to allow the instructor to understand your work, all your calculations, assumptions, and variables. Underline your final results. Scan your work into a worksheet in a PDF file and submit it by uploading it to the assignment link (all your work in only one file). Name your worksheet as follows: lastname_assignment1Ch2-SP23.pdf (ex: Goodrich_Assignment1Ch2-SP23.pdf) Problem \#1A (Similar to problem 2.13 in textbook) In a three-step assembly process (P1, P2 and P3 ), similar to the one described in problem 2.13 textbook, the material manager is required to fulfill 1,500 units (demand) of car seats to its main customer. Find the following: a. Draw the process diagram showing all inputs/outputs, and defective rate per module. b. Draw the chart showing the formula or value of each variable. 3. Work the problem backwards to determine the required level of raw material input (I1) to meet this demand considering the scrap rates for each step (note d1=10%,d2=15% and d3=20% ). d. Note how many units of scrap is produced at each step of the process? (Decimal is ok. E.g., 3.1) e. The finished product can be sold for $100 in the market. If scrap cost is $3 at process 1,$5 at process 2,$7 at process 3 , what is the total cost of scrap
