Question: If 1 ounce of Dawn liquid soap can make 200,000 bubbles, and Dr. Bronner's liquid soap can make twice as many bubbles per ounce as Dawn liquid soap, then how many bubbles can be made from one half ounce of an equal mixture of Dawn and Dr. Bronner's liquid soaps?
Answer: One half of a 1 / 2 - ounce liquid is (1 / 2) * (1 / 2) = 1 / 4 ounces. 1 / 4 ounce of Dawn liquid soap can make (1 / 4) * 200,000 = 50,000 bubbles. 1 / 4 ounce of Dr. Bronner's liquid soap can make 2 * (1 / 4) * 200,000 = 100,000 bubbles. Therefore, a half ounce of an equal mixture of Dawn and Dr. Bronner's liquid soaps can make 50,000 + 100,000 = 150,000 bubbles. The answer is 150000.

Question: Lisa makes breakfast for her family every morning, Monday through Friday. She makes 2 eggs for each of her 4 children and 3 eggs for her husband. Then, she makes 2 eggs for herself. How many eggs does Lisa cook for her family for breakfast in a year?
Answer: Lisa makes 2 eggs / child x 4 children = 8 eggs for her children. She makes 3 eggs for her husband + 2 for herself + 8 for her children = 13 eggs. Lisa makes breakfast 5 days a week for 52 weeks a year, so 5 * 52 = 260 breakfasts. So Lisa makes 13 eggs / breakfast x 260 breakfasts = 3,380 eggs. The answer is 3380.
