Помогите очень надо!!! Для покупки порции мороженого у Пети не хватало 7 рублей,а у Маши одного рубля. Тогда они сложили имевшиеся у них деньги. Но их так же не хватило на покупку 1 порции мороженого. Сколько стоила порция мороженого?

Answer 1

Answer 2

Problem Analysis

To solve this problem, we need to determine the cost of one portion of ice cream based on the given information.

Given Information

- Petya was 7 rubles short of buying a portion of ice cream. - Masha had only 1 ruble. - They combined their money, but it was still not enough to buy one portion of ice cream.

Solution

Let's assume the cost of one portion of ice cream is x rubles.

According to the given information, Petya was 7 rubles short of buying a portion of ice cream, and Masha had only 1 ruble. When they combined their money, it was still not enough to buy one portion of ice cream.

We can set up the following equation to represent the situation:

Petya's money + Masha's money = Cost of one portion of ice cream

Petya's money = x - 7 rubles (since he was 7 rubles short) Masha's money = 1 ruble

Combining their money, we have:

(x - 7) + 1 = x

Simplifying the equation:

x - 6 = x

Subtracting x from both sides:

-6 = 0

This equation has no solution, which means there is no value of x that satisfies the given conditions. Therefore, we cannot determine the cost of one portion of ice cream based on the given information.

Conclusion

Based on the given information, we cannot determine the cost of one portion of ice cream.
