Question

Предположим, что недельный доход Баженова Федора 40 ден. ед. и он расходует его на хлеб и молоко.а) При условии, что цена 1 буханки хлеба 4 ден. ед. (X), а цена 1 литра молока 10 ден. ед. (Y), напишите уравнение бюджетной линии. б) Как изменилось бы уравнение бюджетной линии, если бы доход Федора уменьшился до 20 ден. ед.?в) Сколько буханок хлеба Федор смог бы купить, если бы отказался от молока? (Потребление и спрос).

Answer 1

Решение:

А. Уравнение бюджетной линии: 4 * Qх + 10 * Qм = 40.  

Б. Если доход уменьшится до 20, уравнение бюджетной линии будет выглядеть:
4 * Qх + 10 * Qм = 20.  

В. Если отказаться от молока, то уравнение бюджетной линии будет выглядеть:
4 * Qх + 10 * 0 = 40
4Qх = 40  
Qх = 10 буханок хлеба.

Answer 2

Budget Line Equation

To write the budget line equation, we need to consider the prices of bread and milk and the income of Fedor Bazhenov.

Let's assume the price of one loaf of bread is X (in den. ed.) and the price of one liter of milk is Y (in den. ed.). The weekly income of Fedor Bazhenov is 40 den. ed.

The budget line equation can be written as follows:

40X + 40Y = 40 [[1]]

This equation represents the combination of bread and milk that Fedor can purchase with his weekly income of 40 den. ed.

Changes in the Budget Line Equation

If Fedor's income decreases to 20 den. ed., the budget line equation would change accordingly. The new equation would be:

20X + 20Y = 20

This equation represents the new combination of bread and milk that Fedor can purchase with his reduced income of 20 den. ed.

Bread Quantity without Milk

To determine the number of loaves of bread Fedor could buy if he decided to forgo milk, we need to consider the price of bread and his income.

Given that the price of one loaf of bread is X (in den. ed.) and Fedor's income is 40 den. ed., we can calculate the quantity of bread using the budget line equation.

Substituting the value of Y (price of milk) as 0 in the budget line equation, we get:

40X + 40(0) = 40X = 40

Therefore, Fedor would be able to buy 10 loaves of bread if he decided to only purchase bread and no milk.

Please note that these calculations are based on the given assumptions and prices.
