Question: Jed collects stamp cards. Every week, he gets 6 cards. But every two weeks, he gives 2 cards to his friends. If Jed started with 20 cards, after how many weeks will he have a total of 40 cards?
Answer: Step-by-step reasoning process: In the first week, Jed has 20 + 6 = 26 cards. In the second week, he has 26 + 6 = 32 cards. But he is left with 32 - 2 = 30 cards on the 2nd week after giving 2 cards to his friend. Then Jed has 30 + 6 = 36 cards on the 3rd week. He has 36 + 6 = 42 cards on the 4th week. After giving his friend 2 cards, he is then left with 42 - 2 = 40 cards on the 4th week. Hence, Jed will have a total of 40 cards in 4 weeks.
So the answer is 4.

Question: In the final game of the basketball season, four players scored points. Chandra scored twice as many points as did Akiko. Akiko scored 4 more points than did Michiko, and Michiko scored half as many points as did Bailey. If Bailey scored 14 points, how many points in total did the team score in the final game of the season?
Answer: Step-by-step reasoning process: If Bailey scored 14 points, and Michiko scored half as many points as Bailey, then Michiko scored 14 / 2 = 7 points. If Akiko scored 4 more points than did Michiko, then Akiko scored 7 + 4 = 11 points. Since Chandra scored twice as many points as did Akiko, then Chandra scored 11 * 2 = 22 points. Thus, in total, the team scored 14 + 7 + 11 + 22 = 54 points in total during the final game of the season.
So the answer is 54.

Question: Lindsay has 4 dolls with blonde hair; four times more dolls with brown than blonde hair; 2 fewer dolls with black than brown hair. How many more dolls with black and brown hair combined does Lindsay have than blonde-haired dolls?
Answer: Step-by-step reasoning process: Lindsay has 4 x 4 = 16 brown - haired dolls. She has 16 - 2 = 14 black - haired dolls. Thus, Lindsay has 16 + 14 = 30 black and brown hair dolls combined. Therefore, she has 30 - 4 = 26 more dolls with black and brown hair combined than blonde - haired dolls.
So the answer is 26.

Question: John buys a chair. He then buys a table that is 3 times the price of the chair. Then, he buys a couch that is 5 times the price of the table. If John paid $380 for all these items, what is the price of the couch?
Answer:
Step-by-step reasoning process: Let x be the price of the chair. The table costs 3 * x. The couch costs 3 * x * 5 = 15 * x. x + 3 * x + 15 * x = 380. 19 * x = 380. x = 20. The couch costs 20 * 15 = 300 dollars.
So the answer is 300.
