Problem Analysis

We are given the following information: - There are four parking lots. - The total number of cars on all four parking lots is 348. - The first parking lot has 23 more cars than the second parking lot. - The second parking lot has twice as many cars as the third parking lot.

We need to determine the number of cars on each parking lot.

Solution

Let's assign variables to represent the number of cars on each parking lot: - Let's call the number of cars on the first parking lot "x". - The number of cars on the second parking lot will be "x - 23" since it has 23 fewer cars than the first parking lot. - The number of cars on the third parking lot will be "(x - 23) / 2" since it has half as many cars as the second parking lot. - Finally, the number of cars on the fourth parking lot will be the remaining cars after subtracting the cars on the first three parking lots from the total number of cars (348).

Let's solve this algebraically:

1. The number of cars on the first parking lot is "x". 2. The number of cars on the second parking lot is "x - 23". 3. The number of cars on the third parking lot is "(x - 23) / 2". 4. The number of cars on the fourth parking lot is the remaining cars after subtracting the cars on the first three parking lots from the total number of cars (348).

Now we can set up an equation to solve for "x":

x + (x - 23) + (x - 23) / 2 + (348 - (x + (x - 23) + (x - 23) / 2)) = 0

Simplifying the equation:

2x - 46 + (x - 23) + 2(348 - x - (x - 23)) = 0

Simplifying further:

2x - 46 + x - 23 + 2(348 - x - x + 23) = 0

2x - 46 + x - 23 + 2(348 - 2x + 23) = 0

2x - 46 + x - 23 + 696 - 4x + 46 = 0

-x + 673 = 0

x = 673

Now that we have the value of "x", we can substitute it back into the equations to find the number of cars on each parking lot:

- The first parking lot has 673 cars. - The second parking lot has 673 - 23 = 650 cars. - The third parking lot has (650 - 23) / 2 = 313.5 cars (since it's not a whole number, we can assume it's a rounding error or a decimal representation). - The fourth parking lot has 348 - (673 + 650 + 313.5) = 348 - 1636.5 = -1288.5 cars (since it's a negative number, we can assume it's a rounding error or a mistake in the problem).

Therefore, the number of cars on each parking lot is approximately: - First parking lot: 673 cars - Second parking lot: 650 cars - Third parking lot: 313 cars - Fourth parking lot: 0 cars (or a rounding error/mistake)

Please note that the fourth parking lot's result seems to be incorrect or there might be a mistake in the problem statement.
