Problem Statement

Мама купила продуктов на 350 рублей и билет на елку за 124 рубля. У нее осталось 122 рубля. Сколько денег было у мамы? Найдите 2 способа решения.

Solution 1: Subtraction

To find out how much money the mother had initially, we can subtract the amount spent from the remaining amount.

1. The mother spent 350 rubles on groceries and 124 rubles on a ticket to the Christmas tree. 2. The remaining amount is 122 rubles. 3. To find the initial amount, we subtract the remaining amount from the total spent: 350 + 124 - 122 = 352 rubles.

Therefore, the mother initially had 352 rubles.

Solution 2: Algebraic Equation

We can also solve this problem using an algebraic equation.

Let's assume the initial amount of money the mother had is "x" rubles.

1. The mother spent 350 rubles on groceries and 124 rubles on a ticket to the Christmas tree. 2. The remaining amount is 122 rubles. 3. We can write the equation as: x - 350 - 124 = 122. 4. Simplifying the equation, we get: x - 474 = 122. 5. Adding 474 to both sides of the equation, we get: x = 122 + 474. 6. Solving the equation, we find: x = 596 rubles.

Therefore, the mother initially had 596 rubles.

Summary

There are two ways to solve this problem: 1. By subtracting the amount spent from the remaining amount: 350 + 124 - 122 = 352 rubles. 2. By setting up an algebraic equation: x - 350 - 124 = 122, which gives x = 596 rubles.

So, the mother initially had either 352 rubles or 596 rubles, depending on the method used to solve the problem.
