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

### Instruction:
Julie, Letitia and Anton decided to have dinner together at a nearby restaurant.  Julie orders $10 worth of food, Letitia orders $20 worth of food, and Anton orders $30 worth of food.  How much should each pay in tips if they want to split a 20% tip for the whole meal evenly?

### Response:
 Kwanza, tunahitaji kujua jumla ya bili kabla hatujaamua bahasha. $10 + $20 + $30 = $<<10+20+30=60>>60 ni jumla ya bili.
Sasa tunahitaji kujua jumla ya bahasha. $60 * .20 = $<<60*.20=12>>12 ni jumla ya bahasha.
Sasa tunahitaji kugawanya jumla ya bahasha sawa kwa watu watatu, hivyo $12 / 3 = $<<12/3=4>>4 ndio kiasi ambacho kila mtu anapaswa kuchangia.
