Problem Analysis

We are given the following information: - The total cost of 4.2 kg of sugar and 6.6 kg of cherries is 9.06 r. - The cost of 1 kg of cherries is 0.8 r.

We need to find the cost of 1 kg of sugar.

Solution

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

The cost of 4.2 kg of sugar would be 4.2x r.

The cost of 6.6 kg of cherries would be 6.6 * 0.8 = 5.28 r.

According to the given information, the total cost of 4.2 kg of sugar and 6.6 kg of cherries is 9.06 r.

So, we can write the equation:

4.2x + 5.28 = 9.06

Simplifying the equation:

4.2x = 9.06 - 5.28

4.2x = 3.78

Dividing both sides of the equation by 4.2:

x = 3.78 / 4.2

x = 0.9

Therefore, the cost of 1 kg of sugar is 0.9 r.

Answer

The cost of 1 kg of sugar is 0.9 r.
