Q: Stella’s antique shop has 3 dolls, 2 clocks and 5 glasses for sale. She sells the dolls for $5 each. The clocks are priced at $15 each. The glasses are priced at $4 each. If she spent $40 to buy everything and she sells all of her merchandise, how much profit will she make?
A: The dolls will sell for 3 * $5 = $15. The clocks will bring in 2 * $15 = $30. The glasses will sell for 5 * $4 = $20. In total, she will bring in $15 + $30 + $20 = $65. Her total profit will be $65 - $40 = $25. The answer is 25.

[Answer]There are 30 / 2 = 15 pictures hanging horizontally. So there is a total of 15 + 5 = 20 pictures hanging either horizontally or haphazardly. Therefore, there are 30 – 20 = 10 pictures hanging vertically. The answer is 10.
Q: Rhonda, Sally, and Diane are members of their school's track team. The three of them run the 600-meter relay race together. Rhonda runs the first 200 meters of the race, Sally runs the second 200 meters of the race, and Diane runs the final 200 meters of the race. Rhonda can run 200 meters in 24 seconds. Sally takes two seconds longer to run the same distance, while Diane can run 200 meters three seconds faster than Rhonda. How many seconds does it take for the three of them to run the 600-meter relay race?
A: Sally takes 24 + 2 = 26 seconds. Diane takes 24 - 3 = 21 seconds. Thus, the three take 24 + 26 + 21 = 71 seconds to run the 600 - meter relay race. The answer is 71.
Question: A class of 12 students was about to share 108 oranges equally among themselves when it was discovered that 36 of the oranges were bad and had to be thrown away. How many oranges less will each student get now than if no orange had to be thrown away?
Answer:
If the 12 students had shared the 108 oranges, each student would have gotten 108 / 12 = 9 oranges. But 36 were removed so there are 108 - 36 = 72 oranges left. So 12 shared 72 for each to get 72 / 12 = 6 oranges. This is 9 - 6 = 3 less than they would each get if they did not have to throw any orange away. The answer is 3.
