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 cookies for 20% more than it costs to make them. If he sold 50 cookies and earned $60, how much do the cookies cost to make?

### Response:
 Aliuza mikate kwa $1.20 kila mmoja kwa sababu 60 / 50 = <<60/50=1.2>>1.2
Inagharimu $1 kuitengeneza kwa sababu 1.2 / 1.2 = <<1.2/1.2=1>>1
