Answer 1

Х ( кг ) всего продал
30Х - 150 - 100 - 70 = 880
30Х = 880 + 320
30Х = 1200
Х = 40 ( кг )

Calculation of the Number of Apples Sold by the Hedgehog

To calculate the number of apples sold by the hedgehog, we need to consider the costs of gathering the fruits, transporting them to the wolf, and storing them for the mole.

The hedgehog paid the squirrel 150 rubles for gathering the fruits, the wolf 100 rubles for transportation, and the mole 70 rubles for storage. The hedgehog's total profit was 880 rubles.

Let's assume the hedgehog sold x kilograms of apples.

The total cost incurred by the hedgehog for gathering, transportation, and storage can be calculated as follows: - Gathering cost: 150 rubles - Transportation cost: 100 rubles - Storage cost: 70 rubles

The total cost incurred by the hedgehog is the sum of these costs: Total cost = Gathering cost + Transportation cost + Storage cost

The hedgehog's profit can be calculated as follows: Profit = Total revenue - Total cost

We know that the hedgehog sold the apples for 30 rubles per kilogram, so the total revenue can be calculated as follows: Total revenue = Price per kilogram * Number of kilograms sold

Now, let's solve the equation to find the number of kilograms of apples sold by the hedgehog.

Solution:

Let x be the number of kilograms of apples sold by the hedgehog.

Total cost = Gathering cost + Transportation cost + Storage cost = 150 rubles + 100 rubles + 70 rubles = 320 rubles

Total revenue = Price per kilogram * Number of kilograms sold = 30 rubles/kg * x kg = 30x rubles

Profit = Total revenue - Total cost = 880 rubles

Therefore, we can set up the equation: Profit = Total revenue - Total cost 880 rubles = 30x rubles - 320 rubles

Simplifying the equation: 30x rubles = 880 rubles + 320 rubles 30x rubles = 1200 rubles

Dividing both sides of the equation by 30: x = 1200 rubles / 30 rubles x = 40 kilograms

Therefore, the hedgehog sold 40 kilograms of apples.

Answer:

The hedgehog sold 40 kilograms of apples.
