Answer 2

Calculation of the Cost of the Drink

To calculate the cost of the drink, we need to determine the total volume of the mixture and the total cost of the ingredients used.

Given: - 2 liters of syrup costing 88 rubles per liter - 20 liters of spring water costing 2 rubles and 20 kopeks per liter

Calculation of the Total Volume of the Mixture

The total volume of the mixture is the sum of the volumes of the syrup and the water.

Volume of syrup: 2 liters

Volume of water: 20 liters

Total volume of the mixture: 2 liters + 20 liters = 22 liters

Calculation of the Total Cost of the Ingredients

To calculate the total cost of the ingredients, we need to multiply the volume of each ingredient by its respective cost per liter and then sum the costs.

Cost of syrup: 2 liters * 88 rubles per liter = 176 rubles

Cost of water: 20 liters * (2 rubles + 20 kopeks) per liter = 20 liters * 2.20 rubles per liter = 44 rubles

Total cost of the ingredients: 176 rubles + 44 rubles = 220 rubles

Calculation of the Cost of the Drink

The cost of the drink is equal to the total cost of the ingredients divided by the total volume of the mixture.

Cost of the drink: 220 rubles / 22 liters = 10 rubles per liter

Therefore, the cost of the drink is 10 rubles per liter.
