Answer 3

Calculation of Change

To calculate the change that the mother should receive, we need to determine the total cost of the strawberries and subtract it from the amount she paid.

The mother bought 2 kilograms and 400 grams of strawberries. To calculate the total cost, we need to convert the grams to kilograms. There are 1000 grams in a kilogram, so 400 grams is equal to 0.4 kilograms.

The total weight of the strawberries is 2.4 kilograms.

The cost of 1 kilogram of strawberries is 80 rubles

To calculate the total cost, we multiply the weight by the cost per kilogram:

2.4 kilograms * 80 rubles/kilogram = 192 rubles

The mother paid with a 500 ruble note. To calculate the change, we subtract the total cost from the amount paid:

500 rubles - 192 rubles = 308 rubles

Therefore, the mother should receive 308 rubles in change.
