[Question]Mark is a lawyer who works at the county courthouse every day. It takes him 5 minutes to find parking and 3 minutes to walk into the courthouse. 2 days of the week it takes him 30 minutes to get through the metal detector and the other 3 days are less crowded so he gets through in 10 minutes. How long does he spend on all these activities in a week with 5 work days?
[Answer]First find how long Mark spends on parking and walking each day: 5 minutes + 3 minutes = 8 minutes. Then multiply that number by his number of workdays to find the total walking and parking time: 8 minutes / day * 5 days / week = 40 minutes / week. Then multiply the number of long - wait days by the time of each long wait: 2 days / week * 30 minutes / day = 60 minutes / week. Then multiply the number of short - wait days by the time of each short wait: 3 days / week * 10 minutes / day = 30 minutes / week. Then add the length of time Mark spends on each activity to find the total time spent: 30 minutes / week + 60 minutes / week + 40 minutes / week = 130 minutes / week. The answer is 130.
Q: How many shirts should Shenny pack for her next vacation if she's planning to use the same shirt when departing on Monday and returning on Sunday and two different shirts each other day?
A: Between Monday and Sunday there are 7 days. If she will be using the same shirt for 2 days then she will need clothes for 7 - 2 = 5 days. Because she wants to use 2 different shirts each of those 5 days then she needs 2 * 5 = 10 shirts. In total she will need 10 shirts between Tuesday and Saturday and 1 shirt for Monday and Sunday = 11 shirts. The answer is 11.
Question: Mark started the day with 14 buttons. His friend Shane gave him 3 times that amount of buttons. Then his other friend Sam asked if he could have half of Mark's buttons. How many buttons did Mark end up with?

[Question]Arthur wants to sell his basketball card collection and use the money to buy comic books. The store owner tells him that each card is worth 5 cents and comic books cost $6 each. If Arthur sells all 2,000 cards of his and buys as many comic books as he can, how much money does he have leftover?
[Answer]Arthur makes $100 because .05 x 2000 = 100. Arthur can buy 16 comic books because 100 / 6 = 16 and (2 / 3). The comic books cost $96 because 16 x 6 = 96. He has $4 leftover because 100 - 96 = 4. The answer is 4.
Q: Pat's stick is 30 inches long. He covers 7 inches of the stick in dirt. The portion that is not covered in dirt is half as long as Sarah's stick. Jane's stick is two feet shorter than Sarah's stick. How many inches long is Jane's stick?
A: 30 - 7 = 23 inches of Pat's stick is not covered in dirt. Sarah's stick is 23 * 2 = 46 inches long. Jane's stick is 12 * 2 = 24 inches shorter than Sarah's stick. Jane's stick is 46 - 24 = 22 inches long. The answer is 22.
