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

### Instruction:
At Mario's barbershop haircuts are 50% more expensive during the weekends. If Mario paid $18 for his last haircut on Monday, how much he would have paid the day before?

### Response:
 Kwa kuwa kuchana cha Mario Jumatatu kingekuwa ghali zaidi kwa 50% Jumapili au $18 * .50 = $9 zaidi
Hii inamaanisha kuchana cha Jumapili kingekuwa $18 + $9 = $27
