Q: Micah can type 20 words per minute and Isaiah can type 40 words per minute. How many more words can Isaiah type than Micah in an hour?
A: There are 60 minutes in an hour. Micah can type 20 x 60 = 1200 words in an hour. Isaiah can type 40 x 60 = 2400 words in an hour. Isaiah can type 2400 - 1200 = 1200 words more than Micah in an hour. The answer is 1200.
Question: John buys a gaming PC for $1200. He decides to replace the video card in it. He sells the old card for $300 and buys a new one for $500. How much money did he spend on his computer, counting the savings from selling the old card?

[Question]The number of cards in a card game was 500. Two friends Ellis and Orion, playing together, divided the cards in the ratio of 11:9. How many more cards did Ellis get than Orion?
[Answer]The total ratio representing the 500 cards is 11 + 9 = 20. The fraction of the total ratio that represents the number of cards that Ellis got is 11 / 20, and since there were 500 cards, Ellis got 11 / 20 * 500 = 275. If there were 500 cards, and Ellis received 275 cards, Orion received 500 - 275 = 225 cards. The number of cards that Ellis received more than Orion is 275 - 225 = 50 cards. The answer is 50.
Q: Legoland has 5 kangaroos for each koala. If Legoland has 180 kangaroos, how many koalas and kangaroos are there altogether?

Q: Jamie collects glass balls. He had 16 red balls and two times more blue balls. Later on, he lost 6 of the red balls, so he decided to buy some yellow balls to fill up his collection. How many yellow balls did he buy if, after all, he had 74 balls in total?
A:
Jamie had two times more blue balls than red ones, so he had 2 blue / red * 16 red balls = 32 blue balls. He lost 6 red balls so he had only 16 red balls - 6 red balls = 10 red balls. In total he had 32 blue balls + 10 red balls = 42 red and blue balls. He bought 74 balls - 42 red and blue balls = 32 yellow balls. The answer is 32.
