Please assist with Homework Chapter 21 Problem 10 . I keep getting the calculations mixed up. Thank you. Please provide step by step explantion so I can use it for notes

In the following MRP planning schedule for item J, indicate the correct net requirements, planned order receipts, and planned order releases to meet the gross requirements. Lead time is one week. (Leave no cells blank - be certain to enter "0" wherever required.)

**WEEK NUMBER**  
|| 1 | 2 | 3 | 4 | 5 |
|---|---|---|---|---|---|
| **ITEM J** |
| Gross requirements |  |  | 75 | 50 | 70 |
| On hand | 40 |
| Net requirements |  |
| Planned order receipt |  |
| Planned order release |  |

**Table Explanation:**

The accompanying table is designed to guide the calculation for Material Requirements Planning (MRP) for item J over a five-week period. The objective is to determine the net requirements, planned order receipts, and planned order releases to satisfy the given gross requirements. An existing inventory of 40 units is available on hand. Each column under the "Period" header (1 to 5) represents individual weeks where the planning occurs.

**Components of the Table:**

1. **Gross requirements**: Indicates the total demand for item J during each period (weeks 1-5).
2. **Scheduled receipts**: Spaces are provided for scheduling future receipts.
3. **Projected available balance**: Calculated based on current and incoming inventory versus demand.
4. **LT (Lead Time) = 1 week**: The lead time for orders, specifying a one-week delay from order release to order receipt.
5. **SS (Safety Stock) = 0**: Assumes no safety stock is maintained.
6. **Net requirements**: The actual amount needed each week after accounting for what is available.
7. **Planned order receipts**: The number of units planned to be received in a specific period.
8. **Planned order releases (Q = L4L)**: When and how much should be ordered, calculated from the lead time consideration of one week.

Ensure all fields are filled, entering "0" where applicable, to create a comprehensive materials plan for item J.
