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

### Instruction:
Faye had $20. Today, her mother gave her twice as much as her money. If she bought ten cupcakes at $1.50 each and five boxes of cookies at $3 per box, how much money did she have left?

### 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.
