The plant supplier earned $50 x 20 = $<<50*20=1000>>1000 for the orchids.
He earned $25 x 15 = $<<25*15=375>>375 for the potted Chinese money plants.
So, his total earnings was $1000 + $375 = $<<1000+375=1375>>1375.
Then he paid $40 x 2 = $<<40*2=80>>80 to his workers.
He used a total of $80 + $150 = $<<80+150=230>>230 for the worker's pay and new pots.
Hence, he was left with $1375 - $230 = $<<1145=1145>>1145 from his earnings.
