Let's assume the price of the chair is C.
Then the price of the table is 3C.
And the price of the couch is 5 times the price of the table, so it is 5(3C) = 15C.
John paid a total of $380 for all these items.
So C + 3C + 15C = $380.
Combining like terms, this simplifies to 19C = $380.
Dividing both sides by 19, we find that C = $20.
Therefore, the price of the couch is 15C = 15($20) = $300.
#### 300
The answer is: 300
