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

### Instruction:
Kiki likes to spend her money on hats and scarves. When she buys twice as many hats as scarves, she spends 60% of her money on hats and the rest on scarves. If she currently has $90, how many scarves will she buy if they are sold at $2 each?

### Response:
 Ikiwa Kiki anatumia 60% ya pesa zake kununua kofia, anatumia 40% ya pesa zake kununua skafu kwa sababu 100 - 60 = <<100-60=40>>40
Ikiwa anapaswa kutumia 40% ya pesa zake kununua skafu, atatumia 40/100*$90=$<<40/100*90=36>>36
Kwa pesa $36, Kiki atanunua skafu 18 kwa sababu 36/2 = <<36/2=18>>18
