Question

Для покупки карандаша Кате не хватило 2 копеек, Саше 37 копеек, а а Феде 38 копеек.Когда они сложили все свои деньги, их все равно не хватило на карандаш.Сколько стоил карандаш?

Answer 1

Пусть Х стоимость карандаша, тогда
у кати Х-2 денег,
у Саши Х-37,
у Феди Х-38.
Они сложили все свои деньги, значит: Х-2+Х-37+Х-38 - общая сумма,  им не хватило денег все равно следовательно общая сумма должна быть меньше Х, т.е. Х-2+Х-37+Х-38 < Х Х<38.5  , значит карандаш стоит 38 копеек.

Answer 2

Calculation of the Cost of the Pencil

To calculate the cost of the pencil, we need to determine the total amount of money that Kate, Sasha, and Fyodor had.

Kate was short by 2 kopeks, Sasha had 37 kopeks, and Fyodor had 38 kopeks. When they combined all their money, it was still not enough to buy the pencil.

To find the cost of the pencil, we can subtract the total amount of money they had from the amount they needed. Let's calculate it step by step:

1. Kate was short by 2 kopeks. 2. Sasha had 37 kopeks. 3. Fyodor had 38 kopeks.

To find the total amount of money they had, we add up the amounts:

2 kopeks (Kate) + 37 kopeks (Sasha) + 38 kopeks (Fyodor) = 77 kopeks.

However, this total amount was still not enough to buy the pencil.

Unfortunately, the exact cost of the pencil is not provided in the question. Without knowing the price of the pencil, we cannot determine its cost.
