Answer 2

Problem Analysis

We are given two parking lots, and initially, one parking lot had four times fewer cars than the other. Then, 12 cars were moved from the second parking lot to the first, resulting in an equal number of cars in both parking lots. We need to determine the initial number of cars in each parking lot.

Solution

Let's assume the initial number of cars in the first parking lot is x. Since the second parking lot had four times fewer cars, the initial number of cars in the second parking lot would be 4x.

After moving 12 cars from the second parking lot to the first, the number of cars in both parking lots became equal. Therefore, we can set up the following equation:

x + 12 = 4x

Solving this equation will give us the initial number of cars in the first parking lot (x) and the second parking lot (4x).

Calculation

Let's solve the equation:

x + 12 = 4x

Subtracting x from both sides:

12 = 3x

Dividing both sides by 3:

x = 4

Therefore, the initial number of cars in the first parking lot was 4, and the initial number of cars in the second parking lot was 4 * 4 = 16.

Answer

The initial number of cars in each parking lot was: - First parking lot: 4 cars - Second parking lot: 16 cars
