Answer 2

Problem Analysis

We are given that 4 kg of sugar and 5 kg of apples were purchased for a total of 6.8 rubles. We need to find the cost of 1 kg of sugar, given that 1 kg of apples costs 0.6 rubles.

Solution

Let's assume the cost of 1 kg of sugar is x rubles.

The cost of 4 kg of sugar would be 4x rubles.

The cost of 5 kg of apples would be 5 * 0.6 = 3 rubles.

According to the given information, the total cost of 4 kg of sugar and 5 kg of apples is 6.8 rubles.

So, we can write the equation:

4x + 3 = 6.8

Simplifying the equation:

4x = 6.8 - 3

4x = 3.8

Dividing both sides of the equation by 4:

x = 3.8 / 4

x = 0.95

Therefore, the cost of 1 kg of sugar is 0.95 rubles.

Answer

The cost of 1 kg of sugar is 0.95 rubles.
