Harper collected 30% more pieces of Halloween candy than her sister Maggie, who only collected 50 pieces. Neil collected 40% more candy than Harper. How much candy did Neil get on Halloween? Give the rationale and then the answer.
Let's think step by step. Harper collected 30% more than Maggie’s 50 pieces of candy, so she collected .30 * 50 = 15 more pieces of candy. Maggie has 50 pieces and Harper collected 15 more than her, so she has 50 + 15 = 65 pieces of candy. Neil collected 40% more than Harper, who has 65 pieces, so that’s .40 * 65 = 26 more pieces of candy. Harper has 65 pieces and Neil collected 26 more than her, so he has 65 + 26 = 91 pieces of candy.. The answer is: 91.

An old car can drive 8 miles in one hour. After 5 hours of constant driving, the car needs to get cooled down which takes 1 hour. How many miles can this car drive in 13 hours? Give the rationale and then the answer.
Let's think step by step. In 5 hours the car can drive 8 * 5 = 40 miles. One cycle of driving and pause takes 5 + 1 = 6 hours. In 13 hours this cycle can fit 13 / 6 = 2 full cycles with a remainder of 1 hour. Two cycles will last for 2 * 6 = 12 hours. During two full cycles, the car will drive 40 * 2 = 80 miles. So there is 13 - 12 = 1 remaining hour when the car can drive. That means during 13 hours the car will be able to drive 80 + 8 = 88 miles.. The answer is: 88.

Jerry charges $20 to pierce someone's nose and 50% more to pierce their ears. If he pierces 6 noses and 9 ears, how much money does he make? Give the rationale and then the answer.

Let's think step by step. First find how much more Jerry charges to pierce one person's ears than their nose: $20 * 50% = $10. Then add that amount to the cost of nose piercing to find the total cost: $10 + $20 = $30. Then multiply that price by the number of ears he pierces to find his total earnings from ear - piercing: $30 / ear * 9 ears = $270. Then multiply the price of nose - piercing by the number of noses pierced: $20 / nose * 6 noses = $120. Then add the money from nose - piercing to the money from ear - piercing to find Jerry's total income: $120 + $270 = $390.. The answer is: 390.
