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

### Instruction:
Lyle wants to buy himself and his friends a sandwich and a pack of juice. A sandwich costs $0.30 while a pack of juice costs $0.2. If Lyle has $2.50, how many of his friends can have a sandwich and a pack of juice?

### 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.
