[Question]Jon's laundry machine can do 5 pounds of laundry at a time. 4 shirts weigh 1 pound and 2 pairs of pants weigh 1 pound. If he needs to wash 20 shirts and 20 pants, how many loads of laundry does he have to do?
[Answer]The shirts weigh 20 / 4 = 5 pounds. The pants weigh 20 / 2 = 10 pounds. So he needs to do 10 + 5 = 15 pounds of laundry. So that would take 15 / 5 = 3 loads of laundry. The answer is 3.
Q: Two days ago, Uncle Welly planted 50 roses on his vacant lot. Yesterday, he planted 20 more roses than the previous day. Today, he planted twice the number of roses than two days ago. How many roses did Uncle Welly plant in his vacant lot?
A: Yesterday, Uncle Welly was able to plant 50 + 20 = 70 roses. Today, he planted 2 x 50 = 100 roses. Therefore, Uncle Welly has 50 + 70 + 100 = 220 roses planted on his vacant lot. The answer is 220.
Question: Terry's mom brought home 4 different colored dogs from the shelter. The brown dog weighs 4 pounds. The black dog weighs 1 pound more than the brown dog. The white dog weighs twice as much as the brown dog. The grey dog weighs 2 pounds less than the black dog. What's the average weight of all the dogs?
Answer: Since the black dog weighs 1 pound more than the brown dog, the black dog weighs 1 + 4 = 5 pounds. The white dog weighs 4 * 2 = 8 pounds. Because the grey dog weighs 2 pounds less than the black dog, the grey dog weighs 5 - 2 = 3 pounds. The total weight of all dogs is 4 + 5 + 8 + 3 = 20 pounds. The average weight of all the dogs is 20 / 4 = 5 pounds. The answer is 5.
[Question]In a compound, the number of cats is 20% less than the number of dogs. There are also twice as many frogs as the number of dogs in the compound. Calculate the total number of animals present in the compound if there are 160 frogs.
[Answer]There are twice as many frogs as dogs in the compound, meaning there are 160 / 2 = 80 dogs. The total number of frogs and dogs in the compound is 80 + 160 = 240. The number of cats is less than 20% of the number of dogs, which means there are 20 / 100 * 80 = 16 dogs more than the number of cats. Therefore, the number of cats is 80 - 16 = 64 cats. The total number of animals in the compound is 64 cats + 240 dogs and frogs = 304 animals. The answer is 304.
Q: Sharon’s vacation rental has a Keurig coffee machine. She will be there for 40 days. She has 3 cups of coffee (3 coffee pods) every morning. Her coffee pods come 30 pods to a box for $8.00. How much will she spend on coffee to last her for the entire vacation?
A: She'll be on vacation for 40 days and drinks 3 cups of coffee / pods per day for a total of 40 * 3 = 120 coffee pods. Her coffee pods come 30 in a box and she needs 120 coffee pods so that’s 120 / 30 = 4 boxes. Each box costs $8.00 and she needs 4 boxes so that’s 8 * 4 = $32.00. The answer is 32.
Question: Steven is preparing a shipment of boxes to deliver to a customer for his chemical supply business. The products are very delicate and must be carefully packed, so partially filled boxes can’t be shipped. Steven has three trucks that can be sent on each delivery. Each truck can carry a load of no more than 2,000 pounds of cargo. Some of the boxes weigh 10 pounds after being packed, and some of the boxes weigh 40 pounds when packed. Steven’s customer has ordered equal quantities of both the lighter and heavier products. How many boxes of products can Steven ship to his customer in each delivery?
Answer:
Each pair of boxes weighs 40 pounds + 10 pounds, or 50 pounds. Each pair weighs 50 pounds, so the delivery trucks can carry 2000 / 50 pairs of boxes or 40 pairs. Steven has three trucks, so each trip can move 40 * 3 pairs of boxes = 120 pairs of boxes. Each pair is a set of two boxes, so each delivery contains 120 * 2 boxes = 240 boxes. The answer is 240.
