[Question]Dorothy, Julia, and Robert go to the store to buy school supplies. Dorothy buys half as many pens as Julia. Julia buys three times as many pens as Robert. Robert buys 4 pens. If one pen costs $1.50, how much money did the three friends spend in total on pens?
[Answer]Julia buys 4 * 3 = 12 pens. Dorothy buys 12 / 2 = 6 pens. The total number of pens purchased is 4 + 12 + 6 = 22 pens. The total cost of the pens is 22 * $1.50 = $33. The answer is 33.
Q: Mr Castiel prepared 600 boar sausages on the weekend. He ate 2/5 of them on Monday, half of the remaining on Tuesday and saved the rest for Friday. If he ate 3/4 of the remaining boar sausages on Friday, how many sausages are left?
A: On Monday, Mr Castiel ate 2 / 5 * 600 = 240 sausages. The remaining number of sausages after he ate 240 on Monday is 600 - 240 = 360. On Tuesday, he ate half of the remaining sausages, a total of 360 / 2 = 180. The remaining number of sausages that he saved for Friday after eating 180 on Tuesday is 360 - 180 = 180. On Friday, Mr Castiel ate 3 / 4 * 180 = 135 of the sausages he had kept. The remaining number of sausages after he ate 135 on Friday is 180 - 135 = 45. The answer is 45.
Question: Without factoring in the cost of depreciation for his car John made $30,000 doing Uber. When he finally traded in the car he bought for $18,000 he got $6000 back. What was his profit from driving Uber?
Answer: His car depreciated 18000 - 6000 = $12000. So he made a profit of 30000 - 12000 = $18000. The answer is 18000.
[Question]On a road map, 1/4 inch represents 8 miles of actual road distance. The towns of Pence and Hillcrest are represented by points 3 3/8 inches apart on the map. What is the actual distance, in miles, between the towns?
[Answer]If 1 / 4 inch on the map represents 8 miles on real land, 1 inch represents 4 * 8 = 32 miles. Since 1 inch represents 32 miles, 3 inches represent 3 * 32 = 96 miles. 1 / 4 inch represents 8 miles, 1 / 8 inch represents 8 / 2 = 4 miles because 1 / 8 is half of 1 / 4. If 1 / 8 inch represents 4 miles, 3 / 8 of an inch represents 3 * 4 = 12 miles. This means 3 3 / 8 inches on the map translate to 96 + 12 = 108 miles. The answer is 108.
Q: James writes a 3-page letter to 2 different friends twice a week. How many pages does he write a year?

Question: 25% of oysters have pearls in them. Jamie can collect 16 oysters during each dive. How many dives does he have to make to collect 56 pearls?
Answer:
First find how many pearls Jamie collects per dive by multiplying the number of oysters by the chance each oyster has a pearl: .25 pearls / oyster * 16 oysters / dive = 4 pearls / dive. Then divide the number of pearls he wants by the number of pearls per dive to find the number of dives: 56 pearls / 4 pearls / dive = 14 pearls / dive. The answer is 14.
