Question: Milly is figuring out how long she needs to spend studying. She knows that her math homework will take 60 minutes. Her geography homework will take half as long as her math homework, and her science homework will take time equal to the mean amount of time she spent studying math and geography. How many minutes does Milly spend studying?
Answer with step-by-step thinking: First find how long Milly spends studying geography by dividing her math homework time by 2: 60 minutes / 2 = 30 minutes. Now find the total amount of time Milly spent on math and geography: 30 minutes + 60 minutes = 90 minutes. Now calculate the mean amount of time Milly spends on math and geography by dividing the total time spent by the number of subjects, which is 2: 90 minutes / 2 = 45 minutes. Now add the time Milly spent on all three subjects to find the total: 45 minutes + 30 minutes + 60 minutes = 135 minutes.
So the answer is 135.


Question: Pat's Pool Supply has three times as many swimming pools as Pat's Ark & Athletic Wear store. If Pat's Ark & Athletic Wear store has 200 pools, how many pools do they have in total?
Answer with step-by-step thinking: Since Pat's Ark & Athletic Wear store has 200 pools, Pat's Pool Supply has 3 * 200 = 600 swimming pools. Together, they have 600 + 200 = 800 swimming pools.
So the answer is 800.


Question: Bert made 12 sandwiches for his trip. On the first day, he ate half of the sandwiches he made. The next day he ate 2 sandwiches less. How many sandwiches does Bert have left after these two days?
Answer with step-by-step thinking:
On the first day, Bert ate 12 / 2 = 6 sandwiches. The second day he ate 6 - 2 = 4 sandwiches. So in total Bert is left with 12 - 6 - 4 = 2 sandwiches.
So the answer is 2.
