Answer 3

Calculating the Total Number of Cars

To calculate the total number of cars, we can use the information provided about the number of cars each boy has.

Let's denote: - The number of cars Vasiliy has as V - The number of cars Misha has as M - The number of cars Roma has as R

We are given the following information: 1. Vasiliy has 4 cars. 2. Misha has 8 more cars than Vasiliy. 3. Roma has half the number of cars Misha has.

Calculations

- Misha has 8 more cars than Vasiliy: M = V + 8. - Roma has half the number of cars Misha has: R = 0.5M.

Now, we can substitute the value of M from the first equation into the second equation: R = 0.5(V + 8).

To find the total number of cars, we can add the cars each boy has: Total = V + M + R.

Solution

Substituting the values of M and R: Total = V + (V + 8) + 0.5(V + 8).

Solving for V: Total = 2.5V + 12.

Given that Vasiliy has 4 cars, we can calculate the total number of cars: Total = 2.5(4) + 12 = 10 + 12 = 22.

So, the total number of cars the boys have is 22.
