Q: If you buy a dozen of doughnuts, it costs $8; but if you buy 2 dozens, it costs $14. How much will you save from buying 3 sets of 2 dozens than buying 6 sets of 1 dozen?
A: Six sets of 1 dozen of doughnuts cost $8 x 6 = $48. Three sets of 2 dozens of doughnuts cost $14 x 3 = $42. Therefore, you can save $48 - $42 = $6. The answer is 6.
Question: Today, at the school science lesson, Jake learned that there are 8 more solar systems for every planet in the galaxy. If there are 20 planets in the galaxy, how many solar systems and planets are there altogether?
Answer: If there are 8 more solar systems for every planet in the galaxy, there are 8 + 1 = 9 solar systems for every planet. Since the number of planets is 20, there are 20 * 9 = 180 solar systems in the galaxy. Altogether, there are 180 + 20 = 200 solar systems and planets in the galaxy. The answer is 200.
[Question]Bill is stocking the kitchenware section of the Walmart. He needs to stack 60 pots. On each shelf, he can stack five pots vertically and three sets of vertically stacked pots side-by-side. How many shelves does he need to stock all the pots?
[Answer]First find how many pots fit on one shelf: 5 pots / set * 3 sets = 15 pots. Then divide the number of pots Bill has by the number that fit on each shelf: 60 pots / 15 pots / shelf = 4 shelves. The answer is 4.
Q: Miss Walter has 50 gold stickers. She also has twice as many silver stickers as gold stickers, and 20 fewer bronze stickers than silver stickers. She wants to give the same number of stickers to each of her 5 students. How many stickers will each student receive?
A: She has 50 x 2 = 100 silver stickers. And she also has 100 - 20 = 80 bronze stickers. So, Miss Walter has a total of 50 + 100 + 80 = 230 stickers. Therefore, her 5 students will have 230 / 5 = 46 stickers each. The answer is 46.
