Answer 1

Ответ:

1204 сома

Пошаговое объяснение:

Пусть х сомов было у Динары до этих покупок. Т.к она потратила 245 сомов на салфетки, 567 сомов на полотенца и у нее осталось еще 392 сома, то получим уравнение:

245+567+392=х

812+392=х

1204=х

х=1204 (с) - было у Динары.

Проверка:

1024-245-567=392

392=392

Answer 2

To solve this problem, we can set up an equation to represent the given information. Let's assume that the amount of money Dinar spent on napkins is represented by x, and the amount of money she spent on towels is represented by y. We know that the total amount of money she had before the purchases was 392 soms, and the total amount she spent on napkins and towels was 245 soms + 567 soms = 812 soms. Therefore, we can set up the equation:

x + y = 812

We also know that after the purchases, she had 392 soms left. So we can set up another equation:

x + y = 812 x + y - 812 = 392

Now we can solve this system of equations to find the values of x and y.
