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

### Instruction:
Chastity bought 4 lollipops which cost $1.50 each, and she also bought 2 packs of gummies which cost $2 each. If she has $15, how much was she left with after spending on the candies?

### 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
