I need help understanding how to solve for plant-wide overhead cost. I would like a step by step answer on how to answer the first question and a brief explanation for the second question. After that, I think I will be able to repeat the process on my own. Thanks, Pablo.

Youngstown Products: Youngstown Products, a supplier to the automotive industry, had seen its operating margins shrink below 20% as its OEM customers put continued pressure on pricing. Youngstown produced fours products in its plant and decided to eliminate products that no longer contributed positive margins. Details on the fours products are provided below: A Production Volume Units Selling Price Materials/Unit DLH/unit Total DLH Plant Overhead DL rate/hour B C D 10,000 8,000 6,000 4,000 $15.00 $4.00 0.24 2,400 $18.00 $5.00 0.18 1,440 $20.00 $6.00 0.12 720 $22.00 $7.00 0.08 320 Total 4,880 $122,000 $30/ hr Note: DLH is Direct Labor Hours. Plant overhead is total overhead, treated as a fixed cost. Youngstown has a traditional cost system. It calculates a plant-wide overhead rate by dividing total overhead costs by total direct labor hours. Assume, for the calculations to be made below, that plant overhead is a committed (fixed) cost during the year, but that direct labor is a variable cost. 1. Calculate the plant-wide overhead rate. Use this rate to assign overhead costs to products and calculate the profitability for the four products. You will need to create an excel spreadsheet or working paper to show your calculations and formulas. 2. If any product is unprofitable with this cost assignment, drop this product from the mix. Recalculate the overhead rate based on the new total direct labor hours remaining in the plant. Apply the new overhead rate to the remaining products. 3. Drop any product that is unprofitable with the revised cost assignment. Repeat the process, eliminating any unprofitable products at each stage. 4. What is happening at Youngstown and why? How could this situation be avoided
