Question: Taylor and his friends decide to bring their pets together for a walk. 3 of his friends come first, each having twice as many pets as Taylor has. Another two of his friends have 2 pets each. If Taylor has 4 pets, what's the total number of pets they have together?
Answer: If Taylor has 4 pets, and each of his first friends brings twice as much, the total for each friend is 4 * 2 = 8 pets. The total number of pets for Taylor's first friends is 8 * 3 = 24 pets. The other two friends brought two pets each, a total of 2 * 2 = 4 pets. The total number of pets will be Taylor's pets plus his friend's, which is 4 + 4 + 24 = 32 pets. The answer is 32.
[Question]Daniel has a collection of 346 video games. 80 of them, Daniel bought for $12 each. Of the rest, 50% were bought for $7. All others had a price of $3 each. How much did Daniel spend on all the games in his collection?
[Answer]On 80 games, Daniel spend 80 games * $12 / game = $960. The rest of the collection is 346 games - 80 games = 266 games. 50% of these games means 50 / 100 * 266 games = 133 games. Daniel bought them for $7 each, so he had to spend 133 games * $7 / game = $931 on them. The other 133 games were bought for $3 each, so they've cost him 133 games * $3 / game = $399. On all games in total Daniel spent $960 + $931 + $399 = $2290. The answer is 2290.
Q: Jenny had $24 left after spending 3/7 of her money. How much is half of her original amount of money?
A: Jenny spent 1 - 3 / 7 = 4 / 7 of her money. Since 4 / 7 is equal to $24, then 1 / 7 is equal to $24 / 4 = $6. So, Jenny originally had $6 x 7 = $42. Therefore, half of her original amount of money is $42 / 2 = $21. The answer is 21.
Question: A parking garage near Nora's house is 4 stories tall. There are 100 spots per level. There are 58 open parking spots on the first level. There are 2 more open parking spots on the second level than on the first level, and there are 5 more open parking spots on the third level than on the second level. There are 31 open parking spots on the fourth level. How many full parking spots are there in all?
Answer: There are 4 levels * 100 spots = 400 possible parking spots. The second level has 58 open spots + 2 = 60 open spots. The third level has 60 open spots + 5 = 65 open spots. Total open spots are 58 + 60 + 65 + 31 = 214 open spots. If there are 400 possible spots – 214 open spots = 186 full spots. The answer is 186.
