Answer 2

Calculation of the Number of Passenger Cars in the Fleet

To calculate the number of passenger cars in the fleet, we can use the information provided and solve for the number of passenger cars.

Let's denote: - P as the number of passenger cars - V as the number of cargo (van) cars

Given: - The number of cargo cars is 7 times more than the number of passenger cars: V = 7P - The number of passenger cars is 162 less than the number of cargo cars: P + 162 = V

We can use these two equations to find the value of P.

Solving for the Number of Passenger Cars

Substitute the value of V from the first equation into the second equation: P + 162 = 7P

Now, solve for P: 162 = 6P P = 162 / 6 P = 27

Answer

The number of passenger cars in the fleet is 27.
