Reasoning and answer: There are 23 * 4 = 92 seats on this bus. After the first stop, there are 16 + 15 - 3 = 28 people on the bus. After the 2nd stop, there are 28 + 17 - 10 = 35 people on the bus. So there are 92 - 35 = 57 empty seats on the bus after the 2nd stop.
The answer: 57

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