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

### Instruction:
A store owner buys clothes wholesale and adds 80% to the wholesale price to set the retail price. The retail price of a pair of pants is $36. What is the wholesale price?

### Response:
 Hebu X iwe bei ya jumla.
Bei ya rejareja ya suruali ni X + X*80% = $36.
Hivyo 1.8*X = $36.
Hivyo X = $36 / 1.8 = $20.
