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

### Instruction:
 Lyle anataka kununua sandwich na pakiti ya juisi kwa ajili yake na marafiki zake. Sandwich inagharimu $0.30 wakati pakiti ya juisi inagharimu $0.2. Ikiwa Lyle ana $2.50, marafiki wangapi wanaweza kupata sandwich na pakiti ya juisi?


### Response:
 Sandwich mbili na pakiti mbili za juisi zinagharimu $0.30 + $0.2 = $<<0.3+0.2=0.50>>0.50.
Hivyo, Lyle anaweza kununua $2.50/$0.50 = <<2.5/0.5=5>>5 seti za sandwich na juisi.
Hivyo, 5 - 1 = <<5-1=4>>4 ya marafiki zake wanaweza kupata sandwich na pakiti ya juisi kwani Lyle atakuwa na seti 1.
