[Question]Pauline has 125 matchbox cars. They are all either convertibles, trucks, regular cars. 64% of them are regular cars. 8% are trucks. How many convertibles does she own?
[Answer]The trucks and regular cars make up 72% of her collection because 64 + 8 equals 72. This means convertibles make up 28% of her collection because 100 - 72 equals 28. She has 35 convertibles because 125 times .28 equals 35. The answer is 35.
Q: Gabe has three songs on his playlist. “The Best Day” is 3 minutes, “Raise the Roof” is 2 minutes, and “Rap Battle” is 3 minutes. How many times can Gabe listen to his entire playlist on the 40-minute ride to his wrestling match?
A: If you add all the songs together, Gabe’s playlist is 3 + 2 + 3 = 8 minutes long. During the 40 - minute car ride, Gabe can listen to his 8 - minute playlist 40 / 8 = 5 times. The answer is 5.
Question: Claire is scheduling her day. She has four hours to clean and two hours to cook, then divides the rest of her working day equally between crafting and tailoring. She then sleeps eight hours. If all of this takes place within one day, how many hours did Claire spend crafting?
Answer: We know Claire has spent a total of 24 hours in a day - 4 hours cleaning - 2 hours cooking - 8 hours sleeping = 10 hours crafting and tailoring. Since she split her time equally, she must have spent 10 hours * 0.5 = 5 hours crafting. The answer is 5.
[Question]Mark goes into the store to buy some groceries. He buys 6 2$ cans of soup, 2 $5 loaves of bread, 2 3$ boxes of cereal, and 2 $4 gallons of milk. When he gets to the register, he opens his wallet to pay and realizes he only has $10 bills in there. How many $10 bills does he need to use to pay?
[Answer]Mark buys 6 $2 cans of soup, meaning he spends 6 * 2 = 12 dollars on soup. Mark buys 2 $5 loaves of bread, meaning he spends 2 * 5 = 10 dollars on bread. Mark buys 2 $3 boxes of cereal, meaning he spends 2 * 3 = 6 dollars on cereal. Mark buys 2 $4 gallons of milk, meaning he spends 2 * 4 = 8 dollars on milk. All added together, this means Mark spends 12 + 10 + 6 + 8 = 36 dollars. Since Mark only has $10 bills, he spends 36 / 10 = 3.6 tens on it, which rounds up to 4 as you cannot spend .6 of an undividable item. The answer is 4.
Q: Nancy has six pairs of boots, nine more pairs of slippers than boots, and a number of pairs of heels equal to three times the combined number of slippers and boots. How many shoes (individual shoes, not pairs) does she have?
A: First find how many pairs of slippers Nancy has: 6 pairs + 9 pairs = 15 pairs. Then add that number to the number of pairs of boots she has: 15 pairs + 6 pairs = 21 pairs. Then triple that number to find how many pairs of heels she has: 21 pairs * 3 = 63 pairs. Then add the number of pairs of each kind of shoe she has: 15 pairs + 6 pairs + 63 pairs = 84 pairs. Then multiply the number of pairs by 2 to find the number of individual shoes she has: 84 pairs * 2 shoes / pair = 168 shoes. The answer is 168.
Question: A pet store owner had 12 birds, 9 puppies, 5 cats, and 15 spiders. Half the birds were sold and 3 puppies were adopted. Then, someone left the spider enclosure open and 7 of them went loose. How many animals does the pet store owner have left?
Answer:
There are 12 / 2 = 6 birds left. There are 9 - 3 = 6 puppies left. There are 15 - 7 = 8 spiders left. The pet store owner has 5 + 6 + 6 + 8 = 25 animals left. The answer is 25.
