Please show me how to do it all from all the letters. I would greatly appreciate it.

The demand for subassembly S is 100 units in week 7. Each unit of S requires 2 units of T and 1 unit of U. Each unit of T requires 2 units of V, 2 units of W, and 1 unit of X. Finally, each unit of U requires 2 units of Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 2 weeks to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1 week to make Z.

Suppose that in addition to 100 units of S, there is also a demand for 30 units of U, which is a component of S. The 30 units of U are needed for maintenance purposes. These units are needed in week 6. Additionally, a new order has been received for 70 units of S due in week 8. Modify the net material requirements plan to reflect these changes. Construct a new net material requirements plan (enter your responses as whole numbers).
