Question: Bruno wants to buy two and one-half dozens of pens. How many pens will he have?
Answer: Since a dozen is equal to 12, then two dozens are equal to 12 x 2 = 24. One - half dozen is equal to 12 / 2 = 6. Thus, Bruno will have a total of 24 + 6 = 30 pens. The answer is 30.
[Question]Ryan is considering buying a new multivitamin brand. Each pill has 50 mg of Vitamin A in it. The recommended daily serving of Vitamin A is 200 mg. How many pills does Ryan need to hit the recommended amount for the week?
[Answer]As the daily goal is 200mg and there are 7 days in a week, this means Ryan needs to take 7 * 200 = 1400mg in a week. As there is 50mg per pill, this means Ryan needs to take 1400 / 50 = 28 pills every week. The answer is 28.
Q: Vanessa's new business is thriving and she frequently has orders to post. She has run out of packing peanuts for the packages and is now wondering how many orders she has sent. Each large order needs 200g of packing peanuts while small orders need just 50g of packing peanuts. If Lisa has used a total of 800g of packing peanuts and she knows she has sent 3 large orders, how many small orders has Lisa sent?
A: In the large orders, Lisa used 3 large orders * 200g of packing peanuts per large order = 600g of packing peanuts. The rest of the packing peanuts were used in small orders so there was a total of 800g packing peanuts - 600g of packing peanuts used in large orders = 200g of packing peanuts used in small orders. So there must have been 200g of packing peanuts / 50g of packing peanuts per small order = 4 small orders. The answer is 4.

[Question]The world record for longest fingernails is 26 inches. Sandy, who just turned 12 this month, has a goal for tying the record. Her fingernails are 2 inches long. Her fingernails grow at a rate of one-tenth of an inch per month. How old will she be when she achieves the world record?
[Answer]Sandy's fingernails will grow a total of ( 0.1 ) * 12 = 1.2 inches per year. To achieve the world record, Sandy needs to grow her fingernails a total of 26 - 2 = 24 inches. It will take her a total of 24 / 1.2 = 20 years. Sandy will be 12 + 20 = 32 years old when she achieves the world record. The answer is 32.
