Q: The population of Port Perry is seven times as many as the population of Wellington. The population of Port Perry is 800 more than the population of Lazy Harbor. If Wellington has a population of 900, how many people live in Port Perry and Lazy Harbor combined?
A: Population of Port Perry is 900 * 7 = 6,300. Population of Lazy Harbor is 6,300 - 800 = 5,500. Combined population is 6,300 + 5,500 = 11,800. The answer is 11800.

Q: Anna is reading a 31-chapter textbook, but she skips all the chapters that are divisible by 3. If it takes her 20 minutes to read each chapter, how many hours does she spend reading total?
A: First divide 32 by 3, ignoring the remainder, to find how many chapters in the book are divisible by 3: 31 / 3 = 10.33..., which means 10 chapters are divisible by 3. Then subtract that number from the total number of chapters to find how many chapters she reads: 31 chapters - 10 chapters = 21 chapters. Then multiply the number chapters by the time to read each chapter to find the total time she spends reading: 21 chapters * 20 minutes / chapter = 420 minutes. Then divide that time by the number of minutes per movie to find the total time spent reading in hours: 420 minutes / 60 minutes / hour = 7 hours. The answer is 7.

Q: Last year Jessica paid $1000 for rent, $200 for food, and $100 for car insurance each month. This year her rent goes up by 30%, food costs increase by 50%, and the cost of her car insurance triples because she was at fault in an accident. How much more does Jessica pay for her expenses over the whole year compared to last year?
A:
First find the increase in rent by multiplying last year's rent by 30%: $1000 * .3 = $300. Then find the food cost increase by multiplying last year's costs by 50%: $200 * .5 = $100. Then find the new car insurance price by multiplying last year's price by 3: $100 * 3 = $300. Then subtract the cost of car insurance last year from this year's price to find the increase: $300 - $100 = $200. Now find how much Jessica's monthly expenses increased by adding the increases in each of the three costs: $300 + $100 + $200 = $600. Now multiply the increase per month by the number of months in a year to find the annual increase: $600 / month * 12 months / year = $7200 / year. The answer is 7200.
