Answer 1

Problem Analysis

We are given the total cost of three packages of flour of the same type, which is 780 rubles. The weight of the first package is 1.5 kg, the second package is 2 kg, and the third package is 3 kg. We need to calculate the cost of each package individually.

Solution

To find the cost of each package, we can divide the total cost by the sum of the weights of all three packages. Then, we can multiply the resulting value by the weight of each package to find the cost of each package individually.

Let's calculate it step by step:

1. Calculate the sum of the weights of all three packages: - 1.5 kg + 2 kg + 3 kg = 6.5 kg

2. Calculate the cost per kilogram of flour: - 780 rubles / 6.5 kg = 120 rubles per kg

3. Calculate the cost of each package individually: - First package: 1.5 kg * 120 rubles/kg = 180 rubles - Second package: 2 kg * 120 rubles/kg = 240 rubles - Third package: 3 kg * 120 rubles/kg = 360 rubles

Answer

The cost of each package individually is as follows: - The first package costs 180 rubles. - The second package costs 240 rubles. - The third package costs 360 rubles.
