Calculation of the Total Cost

To calculate the total cost of the purchase, we need to determine the cost of the cabbage and potatoes separately and then add them together.

Given the information provided: - 1 kg of cabbage costs 29 rubles. - 1 kg of potatoes is 3 times more expensive than cabbage.

Let's calculate the cost of the cabbage and potatoes:

1. Cost of 2 kg of cabbage: - 1 kg of cabbage costs 29 rubles. - Therefore, 2 kg of cabbage will cost 29 rubles x 2 = 58 rubles.

2. Cost of 1 kg of potatoes: - Since 1 kg of potatoes is 3 times more expensive than cabbage, we can calculate the cost of 1 kg of potatoes by dividing the cost of cabbage by 3. - 29 rubles (cost of 1 kg of cabbage) / 3 = 9.67 rubles (rounded to two decimal places).

3. Cost of 1 kg of potatoes: - 1 kg of potatoes costs 9.67 rubles.

Now, let's calculate the total cost of the purchase by adding the cost of cabbage and potatoes:

- Total cost = Cost of 2 kg of cabbage + Cost of 1 kg of potatoes - Total cost = 58 rubles + 9.67 rubles = 67.67 rubles.

Therefore, the total cost of the purchase, including 2 kg of cabbage and 1 kg of potatoes, is 67.67 rubles.
