Question: John has taken 10 pictures every day for the past 3 years. He saves them in raw format so each memory card can store 50 images. Each memory card costs $60. How much does he spend on memory cards?
Answer: He takes pictures for 3 * 365 = 1095 days. So he takes 10 * 1095 = 10,950 pictures. That means he needs 10950 / 50 = 219 memory cards. So he spends 219 * 60 = $13140 on memory cards. The answer is 13140.
[Question]John gets lost on his way home. His normal trip is 150 miles and would take him 3 hours. He ends up driving 50 miles out of the way and has to get back on track. How long did the trip take if he kept the same speed?
[Answer]His speed is 150 / 3 = 50 mph. He was detoured 50 * 2 = 100 miles. So that adds 100 / 50 = 2 hours. So the total trip was 3 + 2 = 5 hours. The answer is 5.
Q: If Mr. Jones has 6 shirts for every pair of pants, and he has 40 pants, what's the total number of pieces of clothes he owns if all other factors remain the same?
A: If Mr. Jones has 6 shirts for every pair of pants, and he has 40 pants, the total number of shirts he has is 6 * 40 = 240. The total number of pieces of clothes he owns is 240 + 40 = 280. The answer is 280.
Question: Jan is making candy necklaces for herself and a few friends. Everyone receives a candy necklace each and each candy necklace is made up of 10 pieces of candies. The pieces of candies come from blocks of candy, which each produce 30 pieces of candy. If Jan breaks down 3 blocks of candy and every single piece of candy from this is used in the candy necklaces, how many friends receive a candy necklace?
Answer: There are a total of 3 blocks of candy * 30 pieces of candy per candy block = 90 pieces of candy. Using this, Jan can create 90 pieces of candy / 10 pieces of candy per candy necklace = 9 candy necklaces. As Jan is keeping a candy necklace too, there must have been enough candy necklaces for 9 candy necklaces – 1 candy necklace for Jan = 8 friends. The answer is 8.
