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

### Instruction:
A gift shop sells bracelets at $15 each, a gold heart necklace at $10,  and a personalized coffee mug at $20.  Raine buys three bracelets, two gold heart necklaces, and one coffee mug for her friends. How much change does Raine get back if she gives a one hundred dollar bill?

### Response:
 Mikufu mitatu inagharimu 3 x $15 = $<<3*15=45>>45.
Shingo mbili za dhahabu zinagharimu 2 x $10 = $<<2*10=20>>20.
Hivyo, jumla ya kiasi ni $45 + $20 + $20 = $<<45+20+20=85>>85.
Hivyo, Raine anapata pesa ya kubadilisha $100 - $85 = $<<100-85=15>>15 baada ya kulipa $85 kwa zawadi.
