[Question]: Mark just got a new puppy that cost $10. He also bought enough food for 3 weeks. He knows the puppy eats 1/3 cup of food a day. A bag of food with 3.5 cups costs $2. How much did all of this cost him?
[Answer]: He needs food for 21 days because 3 x 7 = 21. The puppy will eat 7 cups of food because 21 x (1 / 3) = 7. He needs 2 bags of food because 7 / 3.5 = 2. The food will cost him $4 because 2 x 2 = 4. It will cost $14 in total because 10 + 4 = 14.
So the answer is 14.

[Question]: The largest room in Mrs. McAvoy's house is 45 feet wide and 30 feet long. The smallest room in that same house is 15 feet wide and 8 feet long. What is the difference in area between the largest room and the smallest room?
[Answer]: The area of the largest room is 45 ft x 30 ft = 1350 sq ft. The area of the smallest room is 15 ft x 8 ft = 120 sq ft. The difference between the two is 1350 sq ft - 120 sq ft = 1230 sq ft.
So the answer is 1230.
