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

### Instruction:
 Chastity alinunua pipi 4 ambazo kila moja iligharimu $1.50, na pia alinunua pakiti 2 za gummies ambazo kila moja iligharimu $2. Ikiwa alikuwa na $15, alikuwa na kiasi gani baada ya kutumia kwa pipi?


### Response:
 Alitumia jumla ya 4 x $1.50 = $<<4*1.5=6>>6 kwa pipi.
Pia alitumia jumla ya 2 x $2 = $<<2*2=4>>4 kwa gummies.
Kwa hiyo, Chastity alikuwa na $15 - $10 = $<<15-10=5>>5
