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

### Instruction:
 Jessica ana hamu ya vitafunwa na kununua batoni 10 za chokoleti, pakiti 10 za gummy bears, na mifuko 20 ya chips za chokoleti. Jumla yake ilikuwa $150. Ikiwa gharama ya pakiti moja ya gummy bears ni $2 na mfuko mmoja wa chips za chokoleti ni $5, chokoleti moja inagharimu kiasi gani?


### 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.
