Question

Летом килограмм клубники стоит 70 рублей. Маша купила 2 кг 100 г клубники. Сколько рублей сдачи она должна получить с 500 рублей?

Answer 1

2 кг 100 г переведем в кг. 2 кг 100 г = 2,1 кг 

1 кг = 70 руб
2,1 кг = х

$x = \frac{2,1*70}{1}$
x = 147 руб стоит 2,1 кг клубники.
1) 500 - 147 = 353 рубля сдача
ОТВЕТ: 353 руб.

Answer 2

Calculation of Change

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

Masha bought 2 kilograms and 100 grams of strawberries. Let's convert this to kilograms:

- 2 kilograms = 2 kilograms - 100 grams = 0.1 kilograms

So, Masha bought a total of 2.1 kilograms of strawberries.

The cost of 1 kilogram of strawberries is 70 rubles Therefore, the cost of 2.1 kilograms of strawberries would be:

2.1 kilograms * 70 rubles per kilogram = 147 rubles

Masha paid with a 500 ruble note. To calculate the change, we subtract the cost of the strawberries from the amount she paid:

500 rubles - 147 rubles = 353 rubles

Therefore, Masha should receive 353 rubles in change.

Answer: Masha should receive 353 rubles in change.
