Calculation of the Cost of the Boat Ticket

To calculate the cost of the boat ticket, let's break down the information given in the question:

1. Olga initially had 336 rubles. 2. She spent a portion of the money on a boat ticket. 3. The boat travels along the Volga River, near the Ipatiev Monastery. 4. After buying the ticket, Olga had 3/5 of the remaining money left. 5. She then spent some of the remaining money on buying postcards with city views. 6. After these expenses, Olga had 20 rubles left.

Let's calculate the cost of the boat ticket step by step:

1. Olga had 336 rubles initially. 2. She spent a portion of the money on the boat ticket. 3. After buying the ticket, she had 3/5 of the remaining money left. 4. She then spent some of the remaining money on postcards. 5. After these expenses, she had 20 rubles left.

To find the cost of the boat ticket, we need to calculate the remaining money after buying the ticket and postcards. We can then subtract this remaining amount from the initial amount Olga had.

Let's calculate the remaining money after buying the ticket and postcards:

1. Olga had 336 rubles initially. 2. She spent a portion of the money on the boat ticket. 3. After buying the ticket, she had 3/5 of the remaining money left. 4. She then spent some of the remaining money on postcards. 5. After these expenses, she had 20 rubles left.

To find the remaining money, we can subtract the expenses from the initial amount:

336 rubles - (expenses) = 20 rubles

Let's solve for the expenses:

336 rubles - (expenses) = 20 rubles

Subtracting 20 rubles from both sides:

336 rubles - 20 rubles = expenses

316 rubles = expenses

So, the expenses for the boat ticket and postcards amount to 316 rubles.

Therefore, the cost of the boat ticket is 316 rubles.
