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

### Instruction:
After working out for 3 hours, three friends go out for lunch. Adam spends two-thirds as much money on lunch as Rick. Rick and Jose eat lunch of the same price. If Jose ate lunch worth $45, what is the cost of lunch for all three?

### Response:
 Ikiwa Jose alikula chakula cha mchana chenye thamani ya $45, basi Rick alikula chakula cha mchana chenye thamani ya $45.
Adam alikula chakula cha mchana chenye thamani ya 2/3*$45 = <<2/3*45=30>>30.
Kwa hiyo, gharama ya chakula cha mchana kwa wote watatu ni $45 + $45 + $30 = $<<45+45+30=120>>120.
