### Instruction:
Lowry sells bonsai. A small bonsai costs $30 and a big bonsai costs $20. If he sold 3 small bonsai and 5 big bonsai, how much did he earn?

### Response:
He earned 3 x $30 = $<<3*30=90>>90 from the small bonsai.
He also earned 5 x $20 = $<<5*20=100>>100 from the big bonsai.
Therefore, he earned a total of $90+$100 = $<<90+100=190>>190.
