Q: The country of Belize had a 5 lane bridge that had 2000 vehicles passing through it every month. They decided to build a new bridge that had twice the capacity of the old one, and the number of vehicles passing through the new one increased by 60% more than the old bridge. If the bridges work concurrently for a year, calculate the total number of vehicles that pass through the two bridges.
A: 62400
Step-by-step reasoning process: In a year with 12 months, the total number of vehicles passing through the old bridge is 2000 * 12 = 24000. The new bridge has a capacity of 60 / 100 * 2000 = 1200 more vehicles passing through it in a month than the old one. The total number of vehicles passing through the new bridge in a month is 2000 + 1200 = 3200. There are 3200 * 12 = 38400 vehicles passing through the new bridge in a year. Altogether, the two bridges have 38400 + 24000 = 62400 vehicles passing through them in a year.

Q: Libby is building an igloo in her backyard using bricks of snow. She builds her igloo in rows, using a total of 10 rows of bricks of snow. The bottom half of the igloo has 12 bricks of snow in each row while the top half of the igloo has 8 bricks of snow in each row. How many bricks of snow did Libby use for her igloo?
A: 100
Step-by-step reasoning process: In the bottom half of the igloo, there are 10 rows / 2 = 5 rows of bricks of snow. So in the bottom half of the igloo, there are 5 rows * 12 bricks of snow in each row = 60 bricks of snow. In the top half of the igloo, there are 5 rows * 8 bricks of snow in each row = 40 bricks of snow. There is therefore a total of 60 + 40 = 100 bricks of snow in the igloo.

Q: Jeremy's uncle gave him $50 to spend on basketball equipment. He bought 5 jerseys that cost $2 each, a basketball that cost $18, and a pair of shorts that cost $8. How much money does Jeremy have left?
A: 14
Step-by-step reasoning process: The cost of the jerseys is 5 jerseys $2 / jersey = $10. The total cost of the jerseys, the basketball, and the shorts is $10 + $18 + $8 = $36. Jeremy has $50 - $36 = $14 left.

Q: Nate got lost looking for his car in the airport parking lot. He had to walk through every row in Section G and Section H to find it. Section G has 15 rows that each hold 10 cars. Section H has 20 rows that each hold 9 cars. If Nate can walk past 11 cars per minute, how many minutes did he spend searching the parking lot?
A: 30
Step-by-step reasoning process: First find the number of cars in Section G by multiplying the number of rows by the number of cars per row: 15 rows * 10 cars / row = 150 cars. Then do the same thing for Section H: 20 rows * 9 cars / row = 180 cars. Then add the two quantities of cars to find the total number of cars Nate walked past: 150 cars + 180 cars = 330 cars. Finally, divide the number of cars Nate passed by the numbers he passes each minute to find how long he spent searching: 330 cars / 11 cars / minute = 30 minutes.
