[Question]: A parking area near Peter's house is 4 stories tall. There are 4 open parking spots on the first level. There are 7 more open parking spots on the second level than on the first level, and there are 6 more open parking spots on the third level than on the second level. There are 14 open parking spots on the fourth level. How many open parking spots are there in all?
[Answer]: The number of open parking spots on the second level is 4 spots + 7 spots = 11 spots. The number of open parking spots on the third level is 11 spots + 6 spots = 17 spots. There are 4 spots + 11 spots + 17 spots + 14 spots = 46 open parking spots in all.
So the answer is 46.

[Question]: George was selling some of his old toys on the internet. He managed to sell 3 little cars and a set of Legos. In total, he earned $45. How much did the Legos set cost, if one little car was sold for $5?
[Answer]: George sold 3 cars, so he earned 3 cars * $5 / car = $15 from them. The lego set cost was then $45 - $15 = $30.
So the answer is 30.

[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.
So the answer is 130.
