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

### 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:
Let X be the price of the chair.
The table costs 3*X.
The couch costs 5*(3*X) = 15*X.
X + 3*X + 15*X = $380.
19*X = $380.
X = $380 / 19 = $20.
The couch costs $20 * 15 = $<<20*15=300>>300.
#### 300
