Question: Harper drinks a 1/2 bottle of mineral water per day. She buys the mineral water by the case at a big box store. They come 24 bottles to a case and are currently on sale for $12.00. If she wants to buy enough cases to last her 240 days, how much will she spend?
Answer: She drinks 1 / 2 bottle a day and there are 24 bottles in a case so a case will last 24 / .5 = 48 days. She needs enough to last her 240 days and 1 case will last her 48 days so she needs 240 / 48 = 5 cases. Each case is on sale for $12.00 and she needs 5 cases so that's 12 * 5 = $60.00. The answer is 60.

Question: Marcus spends 20 minutes giving his dog a bath and half as long blow-drying her. Then he takes her for a walk along a 3-mile trail. If Marcus walks at 6 miles per hour, how much time does he spend with his dog total?
Answer: First find the total amount of time Marcus spends blow - drying his dog: 20 minutes / 2 = 10 minutes. Then find the time Marcus spends walking: 3 miles / 6 miles / hour = .5 hours. Then convert that time to minutes: .5 hours * 60 minutes / hour = 30 minutes. Then add up the time Marcus spends washing, drying and walking to find the total time: 10 minutes + 20 minutes + 30 minutes = 60 minutes. The answer is 60.
