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

### Instruction:
Frank goes to the store to buy some food. He buys 5 chocolate bars and 2 bags of chips. He hands the cashier $20 and gets $4 back as change. If the chocolate bars each cost $2, how much did each bag of chips cost?

### Response:
 Frank alitumia $20 - $4 = $<<20-4=16>>16 kwa batoni za chokoleti na mifuko ya chips.
Alinunua batoni 5 za chokoleti ambazo kila moja inagharimu $2, hivyo batoni za chokoleti ziligharimu 5 * $2 = $<<5*2=10>>10.
Alitumia jumla ya $16 - $10 kwa batoni za chokoleti = $6 kwa mifuko ya chips.
Alinunua mifuko 2 ya chips kwa jumla ya $6, hivyo kila mfuko wa chips uligharimu $6 / 2 = $<<6/2=3>>3.
