Answer 3

Calculating the Number of Cars

To calculate the number of cars in the garage, we can use the information provided about the proportion of buses, trucks, and other cars.

Given: - Total number of vehicles = 72 - Buses = 1/8 of all vehicles - Trucks = 21

We can calculate the number of cars in the garage using the following steps:

1. Calculate the number of buses: - Total buses = (1/8) * 72 - Total buses = 9

2. Calculate the number of other cars: - Total buses + Total trucks = 9 + 21 - Total buses + Total trucks = 30

3. Calculate the number of cars: - Total cars = Total vehicles - Total buses - Total trucks - Total cars = 72 - 30 - Total cars = 42

Therefore, there were 42 cars in the garage.
