Calculating the Cost of Potatoes

To calculate the cost of the potatoes, we can use the information provided.

Step 1: Calculate the total cost of the fish. - The mother bought 2 kg of fish at 42 RUB per kilogram. - So, the total cost of the fish is 2 kg * 42 RUB/kg = 84 RUB .

Step 2: Calculate the remaining amount for the potatoes. - The mother spent a total of 114 RUB. - Therefore, the remaining amount for the potatoes is 114 RUB - 84 RUB = 30 RUB.

Step 3: Calculate the cost of the potatoes. - The mother bought 6 kg of potatoes. - So, the cost of 1 kg of potatoes is 30 RUB / 6 kg = 5 RUB/kg.

Therefore, the cost of the potatoes is 5 RUB per kilogram.
