Problem Analysis

To solve this problem, we need to determine the amount of money in each pocket based on the given information. Let's break down the information provided:

- The total amount of money in both pockets is 28 rubles. - The right pocket contains only two-ruble coins. - The left pocket contains only five-ruble coins.

We need to find out how much money is in each pocket.

Solution

Let's assume the amount of money in the right pocket is x rubles. Since there are only two-ruble coins in the right pocket, the number of coins in the right pocket will be x/2.

The amount of money in the left pocket will be 28 - x rubles. Since there are only five-ruble coins in the left pocket, the number of coins in the left pocket will be (28 - x)/5.

Now, we can set up an equation based on the given information:

x/2 = (28 - x)/5

To solve this equation, we can cross-multiply:

5x = 2(28 - x)

Expanding the equation:

5x = 56 - 2x

Combining like terms:

7x = 56

Dividing both sides by 7:

x = 8

Therefore, the amount of money in the right pocket is 8 rubles.

To find the amount of money in the left pocket, we can substitute the value of x into the equation:

(28 - x)/5 = (28 - 8)/5 = 20/5 = 4

Therefore, the amount of money in the left pocket is 4 rubles.

Answer

Based on the given information, Misha has 8 rubles in the right pocket and 4 rubles in the left pocket.
