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

### Instruction:
Mary and her two friends agreed to evenly pay for the cost of 2 pounds of chicken. Mary's mother went to the grocery and bought the 2-pound chicken, 3 pounds of beef that cost $4 per pound, and a liter of oil that costs $1. If Mary's mother paid a total of $16 for the grocery, how much should Mary and her two friends pay each for the chicken?

### Response:
 Nyama ya ng'ombe paundi 3 inagharimu $4 x 3 = $12.
Mama wa Mary alilipa $12 + $1 kwa mafuta = $13 kwa nyama ya ng'ombe na mafuta.
Hivyo, kuku wa paundi 2 uligharimu $16 - $13 = $3.
Mary na marafiki zake wanapaswa kulipa $3/3 = $1 kila mmoja.
