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

### Instruction:
 Faye alikuwa na $20. Leo, mama yake alimpa mara mbili ya pesa yake. Ikiwa alinunua mikate kumi kwa $1.50 kila moja na masanduku matano ya biskuti kwa $3 kwa kila sanduku, alikuwa na pesa ngapi zilizosalia?


### Response:
 Mama yake Faye alimpa $20 x 2 = $<<20*2=40>>40.
Hivyo, Faye alikuwa na jumla ya $20 + $40 = $<<20+40=60>>60.
Aliitumia $1.50 x 10 = $<<1.5*10=15>>15 kwa mikate.
Pia, alitumia $3 x 5 = $<<3*5=15>>15 kwa masanduku ya biskuti.
Hivyo, Faye alitumia jumla ya $15 + $15 = $<<15+15=30>>30.
Hivyo, Faye ana $60 - $30 = $<<60-30=30>>30 zilizosalia.
