Normally Ann can frost a cake in 5 minutes. However, today she has a sprained wrist and it takes her 8 minutes to frost a cake. How much longer would it take her to frost 10 cakes with her sprained wrist? Give the rationale and then the answer.
Let's think step by step. Normally, it would take her 5 * 10 = 50 minutes. With her sprained wrist it will take her 8 * 10 = 80 minutes. 80 - 50 = 30 more minutes.. The answer is: 30.

Louis is making himself a velvet suit for a formal event. The velvet fabric he chose was $24 per yard. He bought a pattern for $15, and two spools of silver thread for $3 each. If he spent $141 for the pattern, thread, and fabric, how many yards of fabric did he buy? Give the rationale and then the answer.
Let's think step by step. Let V be the number of yards of velvet fabric Louis bought. The silver thread cost 2 * 3 = $6. He spent 24V + 15 + 6 = $141 on the suit. The fabric cost 24V = 141 - 15 - 6 = $120. Thus, Louis bought V = 120 / 24 = 5 yards of fabric.. The answer is: 5.

Tom, an avid stamp collector, has 3,000 stamps in his collection. He is very sad because he lost his job last Friday. His brother, Mike, and best friend, Harry, try to cheer him up with more stamps. Harry’s gift to Tom is 10 more stamps than twice Mike’s gift. If Mike has given Tom 17 stamps, how many stamps does Tom’s collection now have? Give the rationale and then the answer.

Let's think step by step. Twice the number of stamps given by Mike is 17 stamps * 2 = 34 stamps. Harry therefore gave Tom 10 stamps + 34 stamps = 44 stamps. Combining both gifts gives a gift total of 44 stamps + 17 stamps = 61 stamps. The total number of stamps in Tom’s collection is now 3000 stamps + 61 stamps = 3061 stamps.. The answer is: 3061.
