Question

Тренировочная задача 1 [1 балл] У Тани день рождения. Она взяла из копилки x рублей, купила торт за t рублей, а на оставшиеся деньги решила сводить друзей в кино. Билет стоит b рублей. Скольких друзей Таня может сводить в кино? Сколько денег у неё останется?

Answer 1

Программа:
Python:

x, t, b = int(input()), int(input()), int(input())

x -= t

print(x // b)

print(x % b)

Объясение:

В начале вводятся в программу числа x, t, b с клавиатуры. Так как сначала она купила торт за определённую цену, то от x отнимаем t - у Тани остаётся x - t рублей. Количество друзей, которых она может сводить в кино - это количество билетов, которое сможет купить за x - t рублей. Соответственно, x // b  - получаем целую часть при делении x на b, это и будет максимально возможное число билетов, которое Таня может преобрести. А останется у неё после покупки остаток от этого деления - (x - t) % b.

Результат:

500

Problem Analysis

In this problem, we are given the following information: - Tanya has x rubles in her piggy bank. - She buys a cake for t rubles. - She wants to take her friends to the cinema with the remaining money. - The ticket price is b rubles.

We need to determine how many friends Tanya can take to the cinema and how much money she will have left.

Solution

To solve this problem, we need to subtract the cost of the cake from the amount of money Tanya has. Then, we can divide the remaining amount by the ticket price to find out how many friends she can take to the cinema.

Let's calculate the number of friends Tanya can take to the cinema and the amount of money she will have left.

Calculation

Given: - Amount of money in Tanya's piggy bank: x rubles - Cost of the cake: t rubles - Ticket price: b rubles

1. Calculate the remaining amount of money after buying the cake: Remaining money = Amount of money in piggy bank - Cost of the cake

2. Calculate the number of friends Tanya can take to the cinema: Number of friends = Remaining money / Ticket price

3. Calculate the amount of money Tanya will have left: Money left = Remaining money % Ticket price

Let's substitute the given values into the formulas and calculate the results.

Calculation Example

Given: - Amount of money in Tanya's piggy bank (x): 100 rubles - Cost of the cake (t): 50 rubles - Ticket price (b): 20 rubles

1. Calculate the remaining amount of money after buying the cake: Remaining money = 100 rubles - 50 rubles = 50 rubles

2. Calculate the number of friends Tanya can take to the cinema: Number of friends = 50 rubles / 20 rubles = 2 friends

3. Calculate the amount of money Tanya will have left: Money left = 50 rubles % 20 rubles = 10 rubles

Answer

In the given scenario, Tanya can take 2 friends to the cinema, and she will have 10 rubles left.
