[Question]: There are 20 cars lined up at a race. Each of the cars have 2 passengers and a driver, then when the cars go past the race's halfway point, each car gains another passenger. The cars then continue racing, and the race finishes once every single car has passed the finish line. People who get into the cars have to stay inside of them until the race is finished. How many people are in the cars by the end of the race?
[Answer]: There are 2 passengers and a driver in each car, which means that in each car there are 2 passengers + 1 driver = 3 people. This means there are a total of 20 cars * 3 people per car = 60 people in the car at the start of the race. At the halfway point, there is an additional 20 cars * 1 additional passenger = 20 more people. So be the end of the race, there are 60 people at the start of the race + 20 additional people = 80 people in the cars.
So the answer is 80.

[Question]: Mike spent 37 dollars on notebooks. He bought a total of 12 notebooks. He bought 3 red notebooks at 4 dollars each, 2 green notebooks at 2 dollars each, and the rest were blue notebooks. How much does each blue notebook cost?
[Answer]: He bought 12 - 3 - 2 = 7 blue notebooks. He paid 3 * $4 = $12 for red notebooks. He paid 2 * $2 = $4 for green notebooks. He spent $37 - $12 - $4 = $21 on blue notebooks. Each blue notebook costs $21 / 7 = $3.
So the answer is 3.
