Beats by Dre produces Beats Studio3 headphones. Currently, it is week 1 for headphones production and there are currently 40 speakers (As) in stock. We need 400 headphones (As) at the start of week 5. If there are scheduled receipts planned for week 3 and week 4 of 120 As each and A has a lead time of 1 week, when and how large of an order should be placed to meet the requirement of 400 As? a. Week 4, 40 As
b. Week 4, 400 As
c. Week 4, 200 As
d. Week 1, 200 As
e. Week 1, 400 As

Therefore  an order of 120As should be placed at week 4 to meet the requirement of 400​ As at the start of Week 5.

Note: The options given  do not contain the right answer

Explanation:

Week         Quantity               Accumulated Quantity

 1                    40                                        40

 2                      0(No Qty ordered)            40

 3                  120                                       160

 4                  120                                       280  ( Time to  order)

 5                   120                                    400

From the question, we have that  the expectant week is week 5 with a lead time of 1 week.

Therefore, the  order should be made at

Week 5 - 1  =Week 4

The Size of order to be placed = Requirement of 400As- Accumulated Quantity at Week 4

Size of order to be placed = 400 - ( 40+120+120)

=400-280=120As

Therefore  an order of 120As should be placed  as week 4 to meet the requirement of 400​ As at the start of Week 5.
