Answer 2

Calculation of the Total Cost

To calculate the total cost of the apples and tomatoes, we need to determine the cost of each item separately and then add them together.

The mother bought 2 kg of apples at a price of 45 rubles per 1 kg. Therefore, the cost of the apples is: 2 kg * 45 rubles/kg = 90 rubles.

She also bought 3 times more tomatoes than apples, and the price of tomatoes is 9 rubles more than the price of apples. Let's assume the price of tomatoes per kg is x rubles. Then, the cost of the tomatoes can be calculated as follows: 3 * 2 kg * (x + 9 rubles/kg) = 6 kg * (x + 9 rubles/kg) = 6x + 54 rubles.

Calculation of the Change

The mother paid with a 500 ruble note. To calculate the change she should receive, we need to subtract the total cost from the amount paid: Change = Amount paid - Total cost.

In this case, the change can be calculated as follows: Change = 500 rubles - (90 rubles + 6x + 54 rubles) = 356 rubles - 6x.

Please note that we don't have enough information to determine the exact value of x or the change without additional information.
