[Question]The pet store can buy a goldfish for $.25 and sell it for $.75. The owner plans to use the profits from goldfish sales to buy a new tank, which costs $100. After one week, he is 45% short of the price. How many goldfish did he sell that week?
[Answer]He is $45 short because 100 x .45 = 45. He earned $55 off goldfish because 100 - 45 = 55. He makes $.5 profit per goldfish because .75 - .25 = .5. He sold 110 goldfish that week because 55 / .5 = 110. The answer is 110.
Q: Iris’ family is planning a surprise birthday party for her. The party will include her 3 uncles and 4 aunts who have a son and daughter each as well as her brother and mother. In total, how many people are coming to Iris’ birthday party?
A: Each of her aunts and uncles have a family unit of 1 son + 1 daughter + 1 aunt / uncle = 3 people. Iris has a total of 3 uncles + 4 aunts = 7 aunts or uncles in these family units. So among her aunts, uncles, and cousins, there will be 7 family units * 3 people in each family unit = 21 people. Including her mother and brother, there will be a total of 21 people + 1 mother + 1 brother = 23 people coming to her party. The answer is 23.
Question: Mitch is baking a cake and needs 3 cups of flour and two cups of sugar. He doesn't have a one cup scoop, only a 1/3 cup scoop. How many total scoops will he need?
Answer: He needs 9 scoops of flour because 3 / (1 / 3) = 9. He needs 6 scoops of sugar because 2 / (1 / 3) = 6. He needs 15 total scoops because 9 + 6 = 15. The answer is 15.
[Question]Wynter went to her local town bike shop to buy her sister a bicycle as her birthday gift. While at the shop, Wynter counted 50 bicycles and 20 tricycles. How many wheels in total did the vehicles she saw have?
[Answer]The bicycles had a total of 50 bikes * 2 wheels / bike = 100 wheels. There were 20 trikes * 3 wheels / trike = 60 wheels for the tricycles. The total number of wheels is 100 wheels + 60 wheels = 160 wheels. The answer is 160.
Q: Mrs. Fredrickson has 80 chickens where 1/4 are roosters and the rest are hens. Only three-fourths of those hens lay eggs. How many chickens does Mr. Fredrickson have that do not lay eggs?
A: Mrs. Fredrickson has 80 x 1 / 4 = 20 roosters. So he has 80 - 20 = 60 hens. Only 60 x 3 / 4 = 45 of the hens lay eggs. Thus, 60 - 45 = 15 hens do not lay eggs. Therefore, Mr. Fredrickson has a total of 15 hens + 20 roosters = 35 chickens that do not lay eggs. The answer is 35.
Question: Will and Henry go fishing in a river. Will catches 16 catfish and 10 eels. Henry challenges himself to catch 3 trout for every catfish Will catches. Due to environmental concerns, Henry decides to return half his catch after meeting his own challenge. How many fishes do they have altogether now?
Answer:
Will caught 16 + 10 = 26 fishes. Henry caught 3 trout for each catfish Will caught so since Will caught 16 catfish, Henry caught 16 * 3 = 48 trout. Half of 48 trout is (1 / 2) * 48 = 24. Henry returned 24 trout leaving him with 48 - 24 = 24 trout. They now have a total of 26 + 24 = 50 fishes. The answer is 50.
