Johny traveled South 40 miles, then turned East and traveled for 20 more miles than the distance he took to travel to the south. If he turned North and traveled twice the distance he had traveled to the East, calculate the total distance his journey took. Give the rationale and then the answer.
Let's think step by step. If the distance he took traveling to the East is 20 miles more than the distance he took to travel to the south, he took 40 + 20 = 60 miles traveling to the East. Johny's total distance traveling to the south and then to the East is 60 + 40 = 100 miles. The journey to the North was 2 * 60 = 120, twice the distance he took traveling to the East. The whole journey took 100 + 120 = 220 miles.. The answer is: 220.

Travis goes through 2 boxes of cereal a week. If each box costs $3.00 and he eats 2 boxes every week for an entire year, 52 weeks, how much does he spend on cereal? Give the rationale and then the answer.
Let's think step by step. He eats 2 boxes for 52 weeks so he eats 2 * 52 = 104 boxes. Each box costs $3.00 and he buys 104 boxes so he spends 3 * 104 = $312.00.. The answer is: 312.

Andy started out the year weighing 156 pounds. He then grew 3 inches and gained 36 pounds. Andy wasn't happy with his weight and decided to exercise. Over the next 3 months, he lost an eighth of his weight every month. How much less does Andy weigh now than at the beginning of the year? Give the rationale and then the answer.
Let's think step by step. Andy weighed 156 + 36 = 192 pounds after growing taller. An eighth of his weight is 1 / 8 x 192 = 24 pounds. Over the next 3 months, Andy lost 24 x 3 = 72 pounds. He now weighs 192 - 72 = 120 pounds. Andy weighs 156 - 120 = 36 pounds less than at the beginning of the year.. The answer is: 36.
