Q: One white rhino weighs 5100 pounds and one black rhino weighs 1 ton. How many pounds would 7 white rhinos and 8 black rhinos weigh in total?
A: 5100 * 7 = 35,700 pounds. 1 ton = 2000 pounds. 8 * 2000 = 16000 pounds. 35,700 + 16,000 = 51,700. Seven white rhinos and 8 black rhinos would weigh 51,700 pounds. The answer is 51700.
Question: John is a door-to-door salesman. He visits 50 houses a day. 20% of them buy something from them. Of those that buy something half buy a $50 set of knives and the other half buy a $150 set of knives. How much does he sell a week when he works 5 days a week?
Answer: There are 50 * .2 = 10 houses buying from him per day. Of those 10 / 2 = 5 buy each type of knife set. So he gets 5 * 50 = $250 per day from the cheap set. He also gets 5 * 150 = $750 from the expensive set. So he makes a total of 250 + 750 = $1000 per day. That means he makes 1000 * 5 = $5000. The answer is 5000.
[Question]James is trying to avoid eating too much sodium. He's making a recipe that calls for 2 teaspoons of salt and 8 oz of parmesan cheese. Salt has 50 mg of sodium per teaspoon and parmesan has 25 mg of sodium per oz. If he can't reduce the salt, how many fewer ounces of parmesan cheese does he need to use to reduce the total amount of sodium by 1/3rd?
[Answer]First find how much sodium the parmesan has in total by multiply the amount of sodium per ounce by the number of oz: 25 mg / oz * 8 oz = 200 mg. Then use the same process to find how much sodium is in the salt: 50 mg / tsp * 2 tsp = 100 mg. Then find the total sodium in the recipe by adding the sodium from the cheese and the salt: 100 mg + 200 mg = 300 mg. Then multiply the total amount of sodium by 1 / 3 to find how much less sodium James wants: 300 mg * 1 / 3 = 100 mg. Then divide this amount by the amount of sodium per ounce of cheese to find how many fewer ounces of cheese he needs: 100 mg / 25 mg / oz = 4 oz. The answer is 4.
Q: Adam bought 15 apples on Monday. On Tuesday he bought 3 times that quantity. On Wednesday he bought 4 times the quantity he bought on Tuesday. What is the total quantity Adam bought on these three days?
A: On Tuesday, Adam bought 3 * 15 apples = 45 apples. On Wednesday, Adam bought 4 * 45 apples = 180 apples. Adam bought 15 apples + 45 apples + 180 apples = 240 apples on the three days. The answer is 240.
Question: $240 was divided between Kelvin and Samuel. Samuel received 3/4 of the money. From his share, Samuel then spent 1/5 of the original $240 on drinks. How much does Samuel have left?
Answer: Samuel received 3 / 4 of $240, which is $240 * (3 / 4) = $180. He spent 1 / 5 of $240, which is $240 * (1 / 5) = $48. He spent this amount from his own share, so he has $180 - $48 = $132 left. The answer is 132.
