Question and rationale: The question is: Cary walks 3 miles round-trip to the grocery store, where he buys and eats a candy bar with 200 calories. If Cary burns 150 calories per mile walked, what's Cary's net calorie deficit (expressed as a positive number)?
Step-by-step reasoning process: First, find how many calories the walk burned by multiplying the calories burned per mile by the number of miles Cary walked: 3 miles * 150 calories / mile = 450 calories. Then subtract the calories Corey ate to find the net calories Cary burned: 450 calories - 200 calories = 250 calories.

Question and rationale: The question is: Each dandelion produces 300 seeds. 1/3rd of the seeds land in water and die. 1/6 of the starting number are eaten by insects. Half the remainder sprout and are immediately eaten. How many dandelions survive long enough to flower?
Step-by-step reasoning process: First find the number of seeds that land in water: 300 seeds * 1 / 3 = 100 seeds. Then find the number of seeds that are eaten: 300 seeds * 1 / 6 = 50 seeds. Subtract the number of seeds that are destroyed to find the number that sprout: 300 seeds - 100 seeds - 50 seeds = 150 seeds. Then divide that number by 2 to find the number of sprouts that survive: 150 seeds / 2 = 75 seeds.

Question and rationale: The question is: Gus eats 2 eggs-omelet for breakfast. He has an egg salad sandwich made with 3 eggs for lunch. He then has an egg drop soup made with 1 egg for dinner. How many eggs did Gus eat altogether?

Question and rationale:
The question is: Ruth prepared sandwiches. She ate 1 sandwich and gave 2 sandwiches to her brother. Her first cousin arrived and ate 2 sandwiches. Then her two other cousins arrived and ate 1 sandwich each. There were 3 sandwiches left. How many sandwiches did Ruth prepare?
Step-by-step reasoning process: Ruth's two cousins ate a total of 2 x 1 = 2 sandwiches. So there were 3 + 2 = 5 sandwiches left before her two cousins arrived. Before her first cousin arrived, there were 5 + 2 = 7 sandwiches. Ruth and her brother had 1 + 2 = 3 sandwiches altogether. Therefore, Ruth prepared 7 + 3 = 10 sandwiches.".
