Answer 1

1алтын=3коп.

1095*2/5=438коп=4руб 38коп. на перья и бумагу;

1095*1/3=365коп=3руб 65коп. на еду;

1095-(438+365)=292коп=2руб 92коп;

Ответ: 2руб92коп < 3 руб, меньше на 8коп, на оставшиеся деньги купить сапоги студент не сможет.

Answer 2

Calculation of the Student's Expenses

To determine whether the student can afford to buy boots that cost 3 rubles with the remaining money after spending two-fifths on feathers and paper and one-third on bread and kvass, we need to calculate the amount of money left.

Let's break down the student's expenses:

- Two-fifths of the money is spent on feathers and paper. - One-third of the money is spent on bread and kvass.

To calculate the remaining money, we need to subtract these expenses from the total amount of money the student received.

Calculation:

Let's assume the total amount of money the student received for the year is X rubles.

The amount spent on feathers and paper is (2/5)X rubles.

The amount spent on bread and kvass is (1/3)X rubles.

To calculate the remaining money, we subtract the total expenses from the total amount received:

Remaining money = Total amount received - Total expenses

Remaining money = X - [(2/5)X + (1/3)X]

Simplifying the equation:

Remaining money = X - (6/15)X - (5/15)X

Remaining money = X - (11/15)X

Remaining money = (15/15)X - (11/15)X

Remaining money = (4/15)X

Now, we need to check if the remaining money is enough to buy the boots that cost 3 rubles.

If the remaining money is greater than or equal to 3 rubles, the student can afford to buy the boots.

If the remaining money is less than 3 rubles, the student cannot afford to buy the boots.

Conclusion:

To determine whether the student can afford to buy the boots, we need to know the total amount of money the student received for the year (X). Without this information, we cannot provide a definitive answer.

Please provide the total amount of money the student received for the year, and I will be able to calculate whether the student can afford to buy the boots.
