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

### Instruction:
John buys a chair. He then buys a table that is 3 times the price of the chair. Then, he buys a couch that is 5 times the price of the table. If John paid $380 for all these items, what is the price of the couch?

### Response:
 Hebu x iwe bei ya kiti. Meza inagharimu 3*x na sofa inagharimu 5*3*x = 5*3*x = 15*x.
x + 3*x + 15*x = $380
19*x = $380
x = $380 / 19 = $20
Sofa inagharimu 15 * x = 15 * $20 = $<<15*20=300>>300
