Step-by-step reasoning process: Zoe ate 12 strawberries x 4 calories each = 48 calories. Zoe ate 6 ounces of yogurt x 17 calories per ounce = 102 calories. Zoe at a total of 48 calories + 102 calories = 150 calories.
The question and answer:

Step-by-step reasoning process: If there are 184 cows, twice the number of dogs, then there are 184 / 2 = 92 dogs on the farm. When the farm owner decided to sell 1 / 4 of cows, he sold 1 / 4 * 184 = 46 cows. The total number of cows remaining on the farm is 184 - 46 = 138. If the farm owner also sold 3 / 4 of the dogs, he sold 3 / 4 * 92 = 69. The total number of dogs remaining on the farm is 92 - 69 = 23. The total number of animals remaining on the farm is 23 + 138 = 161.
The question and answer:
Question and answer: There are twice as many cows as dogs at a petting farm. If there are currently 184 cows at the farm, and the farm owner decides to sell 1/4 of the cows and 3/4 of the dogs, how many animals are remaining on the farm?
The answer is 161

Step-by-step reasoning process: We start with the initial numbers of students, 40 and multiply that by .8 for 40 * 0.8 = 32 who own puppies. That the number of students with puppies, 32, and multiply that by .25 to find out how many own both puppies and parrots, 32 * 0.25 = 8 who own puppies and parrots. The answer is 8.
