Calculation of the Total Cost

To calculate the total cost of the purchase, we need to determine the prices of 1 liter of milk and 1 kilogram of cottage cheese. According to the given information, the price of 1 liter of milk is lower than the price of 1 kilogram of cottage cheese by 60%.

Let's assume the price of 1 kilogram of cottage cheese is X. Then the price of 1 liter of milk would be 0.6X, as it is 60% lower than the price of cottage cheese.

The total cost of the purchase can be calculated by multiplying the quantities purchased with their respective prices. The owner bought 2 liters of milk and 700 grams of cottage cheese.

To convert grams to kilograms, we divide the quantity of cottage cheese by 1000. Therefore, the owner bought 0.7 kilograms of cottage cheese.

Now, let's calculate the total cost:

- Cost of 2 liters of milk: 2 liters * price of 1 liter of milk (0.6X) - Cost of 0.7 kilograms of cottage cheese: 0.7 kilograms * price of 1 kilogram of cottage cheese (X)

Adding these two costs together will give us the total cost of the purchase.

Calculation Steps

1. Let's assume the price of 1 kilogram of cottage cheese is X. 2. The price of 1 liter of milk is 0.6X (60% lower than the price of cottage cheese). 3. The owner bought 2 liters of milk and 0.7 kilograms of cottage cheese. 4. The cost of 2 liters of milk is 2 * 0.6X = 1.2X. 5. The cost of 0.7 kilograms of cottage cheese is 0.7X. 6. The total cost of the purchase is 1.2X + 0.7X = 1.9X.

Therefore, the total cost of the purchase is 1.9X.

Please note that the actual value of X (the price of 1 kilogram of cottage cheese) is not provided in the question, so we cannot determine the exact total cost without that information.
