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

### Instruction:
 Mac anapenda umbo la robo na yuko tayari kubadilishana pesa kwa robo hizo, hata kama anapoteza thamani. Anamwambia ndugu yake kuwa atabadilishana naye dimes 3 kwa robo au nickels 7. Anabadilishana robo 20 kwa dimes na robo 20 kwa nickels. Mac alipoteza pesa ngapi?



### Response:
 Dimes 3 ni sawa na $0.3 kwa sababu 3 x .1 = <<3*.1=.3>>0.3
Nickels 7 ni sawa na $0.35 kwa sababu 7 x .05 = .35
Kila mara anapobadilishana na dimes anapoteza $0.05 kwa sababu 0.3 - 0.25 = <<.3-.25=.05>>0.05
Kila mara anapobadilishana na nickels anapoteza $0.1 kwa sababu 0.35 - 0.25 = <<.35-.25=.1>>0.1
Anapoteza $1 kwa kubadilishana na dimes kwa sababu 20 x 0.05 = <<20*.05=1>>1
Anapoteza $2 kwa kubadilishana na nickels kwa sababu 20 x 0.1 = <<20*.1=2>>2
Jumla alipoteza $3 kwa sababu 1 + 2 = <<1+2=3>>3
