Answer 2

Calculation of the Total Number of Cars in the Garage

To calculate the total number of cars in the garage, we need to determine the number of cars of each type and then add them together.

Let's denote the total number of cars in the garage as T.

According to the given information: - The car model "Kalina" constitutes 2/10 of all the cars in the garage. - The car model "Renault" constitutes 3/10 of all the cars in the garage. - The remaining 120 cars are of the "Priora" brand.

To calculate the number of cars of each type, we can set up the following equations:

1. The number of "Kalina" cars: 2/10 * T 2. The number of "Renault" cars: 3/10 * T 3. The number of "Priora" cars: 120

To find the total number of cars in the garage, we can sum up the number of cars of each type:

2/10 * T + 3/10 * T + 120 = T

Now, let's solve this equation to find the value of T.

Solving the Equation

To solve the equation, we can simplify it by combining like terms:

2/10 * T + 3/10 * T = T - 120

Multiplying both sides of the equation by 10 to eliminate the fractions:

2T + 3T = 10T - 1200

Simplifying further:

5T = 10T - 1200

Subtracting 10T from both sides:

-5T = -1200

Dividing both sides by -5:

T = 240

Therefore, the total number of cars in the garage is 240.

Answer

There were a total of 240 cars in the garage.
