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

### 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:
 Miezi miwili ina wiki 2 x 4 = <<2*4=8>>8.
Kiasi ambacho Lyka anapaswa kuokoa kila wiki kwa miezi miwili ni $160 - $40 = $<<160-40=120>>120.
Hivyo, Lyka anapaswa kuokoa $120/8 = $<<120/8=15>>15 kila wiki.
