Problem Analysis

We are given the following information: - Olga spent part of her money on a ticket for a boat that travels along the Volga River. - After that, she spent 3/5 of the remaining money on buying postcards. - Olga has 20 rubles left.

We need to determine the cost of the boat ticket.

Solution

Let's assume that Olga initially had x rubles.

According to the given information, Olga spent part of her money on a boat ticket, and 3/5 of the remaining money on postcards. This means that after buying the ticket, she had (1 - 3/5) = 2/5 of her money left.

We are also told that Olga has 20 rubles left. Therefore, we can set up the following equation:

2/5 * x = 20

To find the value of x, we can multiply both sides of the equation by 5/2:

x = 20 * 5/2

Now we can calculate the value of x:

x = 50

So, Olga initially had 50 rubles.

To find the cost of the boat ticket, we need to subtract the amount of money Olga has left (20 rubles) from the initial amount (50 rubles):

50 - 20 = 30

Therefore, the cost of the boat ticket is 30 rubles.

Answer

The cost of the boat ticket is 30 rubles.
