There are 20 cars in my building’s parking lot. All of the cars are red or white. 12 of them are red, 15 of them are 4-door, and 4 of them are 2-door and white. How many of the cars are 4-door and red?

11 cars

Step-by-step explanation:

There are 20 cars in my building's parking lot, 15 cars are 4-door, then

20 - 15 = 5 cars are 2-door.

5 cars are 2-door, 4 of them are 2-door and white, then

5 - 4 = 1 car is 2-door and red.

12 cars are red, 1 car is 2-door and red, then

12 - 1 = 11 cars are 4-door and red.

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
