Answer 2

Problem Analysis

We are given that there were a total of 120 vehicles (cars and motorcycles) on a parking lot, and the total number of wheels on these vehicles was 404. We need to determine the number of cars and motorcycles.

Solution

Let's assume that the number of cars is represented by 'C' and the number of motorcycles is represented by 'M'. We can set up the following equations based on the given information:

1. The total number of vehicles: C + M = 120 2. The total number of wheels: 4C + 2M = 404

To solve this system of equations, we can use substitution or elimination method. Let's use the elimination method:

Multiplying the first equation by 2, we get: 2C + 2M = 240

Subtracting the second equation from the above equation, we get: (2C + 2M) - (4C + 2M) = 240 - 404 -2C = -164 C = 82

Substituting the value of C into the first equation, we get: 82 + M = 120 M = 120 - 82 M = 38

Therefore, there were 82 cars and 38 motorcycles on the parking lot.

Answer

There were 82 cars and 38 motorcycles on the parking lot.
