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

### Instruction:
Jessica is having a sweet tooth and bought 10 chocolate bars, 10 packs of gummy bears, and 20 bags of chocolate chips. Her total rang up to $150. If the cost of a pack of gummy bears is $2 and a bag of chocolate chips costs $5, how much does 1 chocolate bar cost?

### Response:
 Gummy bears zinagharimu 10 * 2 = $<<10*2=20>>20.
Chips za chokoleti zinagharimu 5 * 20 = $<<5*20=100>>100.
Jumla ya gharama kwa hizi mbili ni 100 + 20 = $<<100+20=120>>120.
Batoni za chokoleti zinagharimu jumla ya 150 - 120 = $<<150-120=30>>30.
Chokoleti moja inagharimu 30 / 10 = $<<30/10=3>>3.
