Q: Michael’s largest watermelon weighs 8 pounds. His neighbor, Clay, grew a watermelon three times that size. And their mutual friend, John, grew a watermelon that was half the size of Clay’s. How big was John’s watermelon?
A: Michael’s watermelon weighs 8 pounds and Clay’s weighs 3 times that so it weighs 8 * 3 = 24 pounds. John’s watermelon is half the size of Clay’s 24 - pound watermelon so it weighs 24 / 2 = 12 pounds. The answer is 12.
Question: Joe plays a soccer tournament with his team. Matches won score 3 points for the winning team and tied matches score 1 point for both teams. Joe and his team won 1 game and drew 3. The first-place team has won 2 games and tied 2. By how many points did the first-place team beat Joe's team?
Answer: For 1 match won, Joe's team scored 1 * 3 = 3 points. For 3 tied games, Joe's team scored 3 * 1 = 3 points. In total, Joe's team scored 3 + 3 = 6 points. For 2 games won, the first - place team scored 2 * 3 = 6 points. For 2 tied games, the first - place team scored 2 * 1 = 2 points. In total, the first - place team scored 6 + 2 = 8 points. The first - place team outscored Joe's team by 8 - 6 = 2 points. The answer is 2.
[Question]In a grocery store, Julia bought 2 pieces of Snickers and 3 packs of M&M's. If each piece of Snickers costs $1.5 and a pack of M&M's has the same cost as 2 Snickers, how much is Julia's change if she gave the cashier 2 $10 bills?
[Answer]Two pieces of snickers cost $1.5 x 2 = $3. One pack of M&M's costs $3 so 3 packs cost $3 x 3 = $9. The total amount that she needs to pay is $3 + $9 = $12. Julia gave the cashier $10 x 2 = $20. So, her change is $20 - $12 = $8. The answer is 8.
Q: Marcus takes a deck of standard playing cards and takes out all the face cards and the 8's. Mark picks a card at random and then replaces it 36 times. How many times should he expect to pick a card that's both red and has a number divisible by 3?
A: Without the face cards and the 8's, there are 9 cards of each suit. Half these cards are red, and 3 / 9 have numbers divisible by 3, so the odds of drawing a card divisible by 3 are 1 / 3. Multiply the odds of drawing a red card by the odds of drawing a card divisible by 3 to find the odds of both things happening: 1 / 3 * 1 / 2 = 1 / 6. Finally, multiplying the probability of drawing a red / 3 - divisible card by the number of cards Mark draws to find how many he should expect to meet his criteria: 1 / 6 * 36 cards = 6 cards. The answer is 6.
Question: Selina is selling some of her old clothes to a second-hand store. They will buy her pants for $5 each, her shorts for $3 each, and her shirts for $4 each. She sells 3 pairs of pants, 5 pairs of shorts, and some shirts. After she gets her money, she sees 2 shirts that she likes which cost $10 each and buys them. She leaves the store with $30. How many shirts did she sell to the store?
Answer: The shirts she bought cost her $20 because 2 x 10 = 20. She earned $50 selling her clothes because 20 + 30 = 50. She made $15 off pants because 3 x 5 = 15. She made 15 dollars from shorts because 3 x 5 = 15. She made $20 off shirts because 50 - 15 - 15 = 20. She sold 5 shirts because 20 / 4 = 5. The answer is 5.
