Problem Analysis

To solve this problem, we need to calculate the total amount of money earned from selling the fruits. We are given that the total weight of the fruits is 80 kg, with three-quarters of the weight being apples and one-quarter being mandarins. The cost of 1 kg of apples is x rubles, which is half the cost of 1 kg of mandarins. We also know that there are a kg of unsold mandarins and b kg of unsold apples.

Solution Steps

To calculate the total amount of money earned from selling the fruits, we can follow these steps:

1. Calculate the weight of apples and mandarins: - Three-quarters of the total weight is apples, so the weight of apples is 3/4 * 80 kg. - One-quarter of the total weight is mandarins, so the weight of mandarins is 1/4 * 80 kg.

2. Calculate the cost of apples and mandarins: - The cost of 1 kg of apples is x rubles. - The cost of 1 kg of mandarins is 2x rubles (twice the cost of apples).

3. Calculate the total amount of money earned from selling the fruits: - Multiply the weight of apples by the cost of 1 kg of apples. - Multiply the weight of mandarins by the cost of 1 kg of mandarins. - Add the two amounts together to get the total amount of money earned.

4. Subtract the value of the unsold fruits: - Multiply the weight of unsold apples (b kg) by the cost of 1 kg of apples. - Multiply the weight of unsold mandarins (a kg) by the cost of 1 kg of mandarins. - Subtract the two amounts from the total amount of money earned to get the final result.

Calculation Steps

Let's calculate the total amount of money earned from selling the fruits using the given values of a, b, and x:

1. Calculate the weight of apples and mandarins: - Weight of apples = 3/4 * 80 kg = 60 kg - Weight of mandarins = 1/4 * 80 kg = 20 kg

2. Calculate the cost of apples and mandarins: - Cost of 1 kg of apples = x rubles - Cost of 1 kg of mandarins = 2x rubles

3. Calculate the total amount of money earned from selling the fruits: - Amount earned from selling apples = Weight of apples * Cost of 1 kg of apples = 60 kg * x rubles - Amount earned from selling mandarins = Weight of mandarins * Cost of 1 kg of mandarins = 20 kg * 2x rubles - Total amount earned = Amount earned from selling apples + Amount earned from selling mandarins = 60x + 40x = 100x rubles

4. Subtract the value of the unsold fruits: - Value of unsold apples = Weight of unsold apples * Cost of 1 kg of apples = b kg * x rubles - Value of unsold mandarins = Weight of unsold mandarins * Cost of 1 kg of mandarins = a kg * 2x rubles - Final amount earned = Total amount earned - (Value of unsold apples + Value of unsold mandarins) = 100x - (bx + 2ax) rubles

Therefore, the program should calculate the final amount earned as 100x - (bx + 2ax) rubles.

Program Implementation

Here's an example of how the program can be implemented in Python:

def calculate_total_earnings(a, b, x):
    weight_apples = (3/4) * 80
    weight_mandarins = (1/4) * 80

cost_apples = x
    cost_mandarins = 2 * x

amount_earned_apples = weight_apples * cost_apples
    amount_earned_mandarins = weight_mandarins * cost_mandarins

total_amount_earned = amount_earned_apples + amount_earned_mandarins

value_unsold_apples = b * cost_apples
    value_unsold_mandarins = a * cost_mandarins

final_amount_earned = total_amount_earned - (value_unsold_apples + value_unsold_mandarins)

return final_amount_earned

# Example usage:
a = 10  # kg of unsold mandarins
b = 5   # kg of unsold apples
x = 10  # cost of 1 kg of apples in rubles

total_earnings = calculate_total_earnings(a, b, x)
print("Total earnings:", total_earnings, "rubles")

In this example, the program takes the values of a, b, and x as inputs and calculates the final amount earned from selling the fruits. The result is then printed as the total earnings in rubles.

Please note that this is just one possible implementation of the program, and there may be other ways to solve the problem.
