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

### Instruction:
 Micheal ameamua kuchukua masomo ya piano. Somo moja linagharimu $30 na linadumu kwa saa 1.5. Micheal atahitaji kulipa kiasi gani kwa masomo ya saa 18?


### Response:
 Somo moja linadumu kwa saa 1.5, hivyo masomo ya saa 18 ni 18 / 1.5 = <<18/1.5=12>>12 masomo.
Ikiwa somo moja linagharimu $30, basi 12 yatagharimu 12 * 30 = $<<12*30=360>>360.
