Question: Aunt Gemma has four dogs. She feeds them with dog food twice a day. Each dog can consume 250 grams of food per meal. If aunt Gemma bought 2 sacks of dog food, each weighing 50 kilograms, how many days will those food last?
Answer: Each dog consumes 250 grams x 2 = 500 grams of dog food each day. So, 4 dogs consume 500 grams x 4 = 2000 grams of dog food each day. Since there are 1000 grams in 1 kilogram, then the 4 dogs can consume 2000 / 1000 = 2 kilograms of dog food each day. Aunt Gemma bought a total of 50 kilograms x 2 = 100 kilograms of dog food. Hence, it will last 100 kilograms / 2 kilograms = 50 days. The answer is 50.

Question: Eric spent 2 hours removing wallpaper from just 1 wall of his 4 walled dining room. He also needs to remove wallpaper from his 4 walled living room. How many hours will it take him to remove the remaining wallpaper?
Answer: His dining room is 4 walls and he has already removed 1 wall of wallpaper so that leaves 4 - 1 = 3 walls in the dining room. He has 3 walls left in the dining room and 4 in his living room for a total of 3 + 4 = 7 walls. It takes 2 hours to remove wallpaper from just 1 wall and he has 7 more to go so it will take him 2 * 7 = 14 hours. The answer is 14.
