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

### Instruction:
Joe sells ham and cheese sandwiches for $1.50. If a slice of bread costs $0.15, a slice of ham costs $0.25 and a slice of cheese costs $0.35, how many cents does a sandwich with one slice of each protein cost Joe to make?

### Response:
 Kwanza tafuta gharama ya vipande viwili vya mkate: $0.15/kipande * vipande 2 = $<<0.15*2=0.30>>0.30
Kisha ongeza gharama ya kipande kimoja cha hamu na jibini: $0.30 + $0.25 + $0.35 = $<<0.30+0.25+0.35=0.90>>0.90
