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? Let's think step by step and output the final answer after "####".

Let x be the price of the chair.
The table costs 3*x.
The couch costs 3*x*5=15*x.
x+3*x+15*x=380
19*x=380
x=<<20=20>>20
The couch costs 20*15=<<20*15=300>>300 dollars.
#### 300
