Question: John is half times younger than his father, who is 4 years older than John's mother. If John's father is 40 years old, what's the age difference between John and his mother?
Answer: John is half times his father's age. Thus 1 / 2 * 40 = 20 years. Since the mother is 4 years younger than the father, she is 40 - 4 = 36 years old. The age difference between John and his mother is 36 - 20 = 16 years. The answer is 16.

Q: Bob has a cube of silver that measures 3 inches on each side. A cubic inch of silver weighs 6 ounces. Each ounce of silver sells for $25. He sells it for 110% of its silver value. How much does he sell it for?
A: The silver has a volume of 3 * 3 * 3 = 27 cubic inches. So it weighs 27 * 6 = 162 ounces. So its value is 162 * 25 = $4050. That means he sold it for 4050 * 1.1 = $4455. The answer is 4455.
Question: Tom invites his parents and 3 siblings to his house. They each eat 3 times a day. How many plates do Tom and his guests use while they are there for the 4 days if each person uses 2 plates per meal?
Answer: There were 1 + 2 + 3 = 6 people at the house. That means they use 6 * 2 = 12 plates per meal. So they use 12 * 3 = 36 plates per day. That means they use 36 * 4 = 144 plates for the visit. The answer is 144.
[Question]A museum has eight different wings displaying four times as many artifacts as paintings displayed. Three of the wings are dedicated to paintings. The artifacts are divided evenly among the remaining wings. One painting is so large it takes up an entire wing, and the other two wings house 12 smaller paintings each. How many artifacts are in each artifact wing?
[Answer]The museum has 2 * 12 + 1 = 25 paintings displayed in the painting wings. There are 4 times as many artifacts displayed, so there are 25 * 4 = 100 artifacts. There are 8 wings and 3 are painting wings, so there are 8 - 3 = 5 artifact wings. Each artifact wing has 100 / 5 = 20 artifacts in it. The answer is 20.
[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.
