Lucy works in a pet shop. She can clean 2 aquariums in 3 hours. If Lucy is working 24 hours this week, how many aquariums could she clean? Give the rationale and then the answer.
Let's think step by step. We know how many aquariums Lucy can clean in a 3 - hour increment. This week, Lucy will work for 24 / 3 = 8 increments. Lucy can clean 2 aquariums per increment, so she can clean 2 x 8 = 16 aquariums.. The answer is: 16.

Mary Anne drinks 1/5 of a bottle of sparkling water every night at dinner. If each bottle costs her $2.00, how much does she spend on sparkling water every year? Give the rationale and then the answer.
Let's think step by step. She drinks 1 / 5 of a bottle of sparkling water every night so over an entire year she drinks .2 * 365 = 73 bottles of sparkling water. Every bottle costs $2.00 and she drinks 73 bottles a year so she spends 2 * 73 = $146.00 a year on sparkling water.. The answer is: 146.

Jorge and Giuliana each eat 7 croissants for breakfast, 18 cakes after school, and 30 pizzas before bedtime. What is the total number of croissants, cakes, and pizzas the two consume in a day? Give the rationale and then the answer.
Let's think step by step. The number of croissants and cakes that each eats for breakfast and lunch respectively is 7 + 18 = 25. After eating 30 pizzas before bedtime, the number of croissants, cakes, and pizzas that each person have in total for the day is 25 + 30 = 55. Since each person eats a total of 55 croissants, cakes, and pizzas for the day, the two consume a total of 55 + 55 = 110 of the food in a day.. The answer is: 110.
