7. (8 pts.) Jedi make their own lightsabers, but we're making knockoffs for tourists; both the three-bladed Kylo Ren kind and the double one that Rey has. In the drawing, you can see the Focusing Crystal used to focus the blade's energy. Production plans for the two-bladed lightsabers for upcoming weeks are given below, and as you can see, we use Lot-for-Lot for this production, and the lead time is 1 week.

Since there is less demand for these, we produce in a fixed order quantity of batches of 10 , and the lead time is 2 weeks. For the two-bladed lightsaber, TWO Focusing Cyrstals are used, and for the three-bladed lightsaber, THREE Focusing Crystals. Compute the Gross Requirements for the Focusing Crystals.
