Problem Analysis

We are given that 15 trucks and 5 cars arrived at a parking lot, and after their arrival, there were 60 vehicles in total. We need to determine the initial number of vehicles on the parking lot.

Solution

Let's assume the initial number of vehicles on the parking lot is x.

According to the given information, 15 trucks and 5 cars arrived at the parking lot. Therefore, the number of vehicles that arrived is 15 + 5 = 20.

After their arrival, the total number of vehicles on the parking lot became 60.

We can set up the following equation to represent the situation:

x + 20 = 60

To find the initial number of vehicles on the parking lot, we need to solve this equation for x.

Calculation

Let's solve the equation:

x + 20 = 60

Subtracting 20 from both sides of the equation:

x = 60 - 20

x = 40

Answer

The initial number of vehicles on the parking lot was 40.
