Question

Из оставшихся 336 рублей несколько Оля отдала за билет на катер,который повез всех по Волге вдоль Ипатьевского монастыря,3\5 оставшихся после этого денег она потратила на покупку открыток с видами городов и получила сдачу 20 рублей.Сколько стоил билет на катер?

Answer 1

возмем за х-билет на катер, тогда

336-х-(336-х)*3/5=20 сдача

336-х-336*3/5+3х/5=20

336-201,6-20=х-3х/5

2х/5=114,4

2х=5*114,4=572

х=572/2=286 руб стоит билет на катер

 

Answer 2

1-3/5=2/5 сдача или 20 руб

20*2/5=50 руб осталось после покупки билета

336-50=286 руб стоил билет

Answer 3

Calculation of the Ticket Price

To calculate the price of the ticket for the boat ride, we need to follow the information provided in the question.

1. Olga spent 3/5 of the remaining money on buying postcards and received 20 rubles in change. 2. Olga had 336 rubles left before buying the postcards.

Let's calculate the ticket price step by step:

1. Calculate the amount of money Olga spent on postcards: - Olga spent 3/5 of the remaining money on postcards. - 3/5 * 336 rubles = 201.6 rubles.

2. Calculate the amount of money Olga had left after buying the postcards: - Olga had 336 rubles before buying the postcards. - She spent 201.6 rubles on postcards. - 336 rubles - 201.6 rubles = 134.4 rubles.

3. Calculate the ticket price: - Olga received 20 rubles in change after buying the postcards. - The remaining money after buying the postcards is 134.4 rubles. - The ticket price is the difference between the remaining money and the change received. - 134.4 rubles - 20 rubles = 114.4 rubles.

Therefore, the ticket for the boat ride cost 114.4 rubles.

Note: The calculation assumes that Olga spent all the remaining money on the boat ticket and postcards, and that there were no other expenses mentioned in the question.
