Below is an instruction that describes a task. Write a response that appropriately completes the request in German. Please answer in German.

### Instruction:
 Lyka wants to buy a smartphone worth $160 but she only has $40 at the moment. She plans to save an equal amount of money per week for two months for the remaining amount that she needs. How much should she save per week?


### Response:
 Zwei Monate haben 2 x 4 = <<2*4=8>>8 Wochen.
Der Betrag, den Lyka pro Woche für zwei Monate sparen muss, beträgt $160 - $40 = $<<160-40=120>>120.
Daher muss Lyka $120/8 = $<<120/8=15>>15 pro Woche sparen.
