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?
Lowry earns $30 x 3 = $<<30*3=90>>90 from selling 3 small bonsai.
He earned $20 x 5 = $<<20*5=100>>100 from selling 5 big bonsai.
Therefore, the total amount he earned is $100 + $90 = $<<100+90=190>>190.
