Answer 2

Calculation of Newspaper Sales

To calculate the total amount of newspaper sales in the kiosk over two days, we need to add the sales from the first day to the sales from the second day.

Let's denote the sales on the first day as x (in rubles and kopeks) and the sales on the second day as y (in rubles and kopeks).

According to the information provided, the sales on the first day were 128 rubles and 60 kopeks, and the sales on the second day were 42 rubles and 40 kopeks more than the first day.

To find the sales on the second day, we can add the additional amount to the sales on the first day:

y = x + 42 rubles and 40 kopeks

Now, we can calculate the total sales over two days by adding the sales from the first day and the sales from the second day:

Total sales = x + y

Let's substitute the value of y into the equation:

Total sales = x + (x + 42 rubles and 40 kopeks)

Simplifying the equation:

Total sales = 2x + 42 rubles and 40 kopeks

Now, we can substitute the given values into the equation to find the total sales:

Total sales = 2 * 128 rubles and 60 kopeks + 42 rubles and 40 kopeks

Calculating the total sales:

Total sales = 257 rubles and 40 kopeks + 42 rubles and 40 kopeks

Total sales = 299 rubles and 80 kopeks

Therefore, the total amount of newspaper sales in the kiosk over two days is 299 rubles and 80 kopeks.

Answer 3

В первый день продали газеты на сумму 128 рублей 60 копеек. Во второй день продали газеты на 42 рубля 40 копеек больше, то есть на 128 рублей 60 копеек + 42 рубля 40 копеек = 171 рубль. За два дня продали газеты на сумму 128 рублей 60 копеек + 171 рубль = 299 рублей 60 копеек.
