Question

Срочно! 30 баллов!Решите экономическую задачу. Безумный Шляпник планирует организовать чаепитие. Помимо него самого приглашены Мартовский Заяц, Алиса, Чеширский Кот и Красная Королева. На каждого участника чаепития нужно приготовить 100 грамм чая и пирожное. В Зазеркалье всего два магазина: одним владеет Гусеница, а другим — Додо. В магазине Гусеницы одно пирожное стоит 11 монет, а килограмм чая — 50 монет. В магазине Додо чай продают по 60 монет за килограмм, а пирожные — по 10 за штуку. Магазин Гусеницы расположен далеко, и придётся заплатить за доставку 10 золотых монет, но Гусеница — хорошая подруга Шляпника и сделает скидку в размере 10 % на сумму покупки (но не доставки). Помогите Шляпнику. 1. Укажите, в каком магазине выгоднее купить всё для чаепития. 2. Укажите одним числом, сколько монет он сэкономит. 3. Укажите одним числом сумму, которую он потратит.

Answer 1

Всего 5 участников: Шляпник, Заяц, Алиса, Кот и Королева.

Значит, нужно 500 г = 0,5 кг чая и 5 пирожных.

В магазине Гусеницы 1 пирожное стоит 11 монет, а 1 кг чая 50 монет.

Значит, Шляпник потратит:

5*11 + 0,5*50 = 55 + 25 = 80 монет без скидки.

А со скидкой 10% он потратит 80*0,9 = 72 монеты.

Плюс 10 монет за доставку, всего 82 монеты.

В магазине Додо 1 пирожное стоит 10 монет, а 1 кг чая 60 монет.

Значит, Шляпник потратит:

5*10 + 0,5*60 = 50 + 30 = 80 монет.

Ответы: 1) Выгоднее купить в магазине Додо.

2) Шляпник сэкономит 2 монеты.

3) Он потратит 80 монет.

Problem Analysis

The Mad Hatter wants to organize a tea party and needs to buy tea and pastries for himself and the other participants. There are two stores in Wonderland: one owned by the Caterpillar and the other by the Dodo. The prices of tea and pastries differ between the two stores, and there is also a delivery cost associated with buying from the Caterpillar's store. We need to determine which store the Mad Hatter should choose to buy everything for the tea party, how much money he will save, and the total amount he will spend.

Solution

To solve this problem, we need to compare the total cost of buying tea and pastries from each store, taking into account the prices and the delivery cost. Let's calculate the cost for each store and compare the results.

1. Which store is more advantageous to buy everything for the tea party?

To determine which store is more advantageous, we need to calculate the total cost of buying tea and pastries from each store.

- Store owned by the Caterpillar: - Price of pastries: 11 coins per pastry - Price of tea: 50 coins per kilogram - Delivery cost: 10 coins - Discount: 10% on the total purchase amount (excluding delivery)

- Store owned by the Dodo: - Price of pastries: 10 coins per pastry - Price of tea: 60 coins per kilogram - No delivery cost or discount

Let's calculate the total cost for each store:

- Store owned by the Caterpillar: - Cost of pastries: 4 participants * 1 pastry/participant * 11 coins/pastry = 44 coins - Cost of tea: 4 participants * 100 grams/participant * (50 coins/1000 grams) = 20 coins - Total cost: 44 coins + 20 coins + 10 coins (delivery) = 74 coins - Discount: 10% of 74 coins = 7.4 coins - Final cost: 74 coins - 7.4 coins = 66.6 coins

- Store owned by the Dodo: - Cost of pastries: 4 participants * 1 pastry/participant * 10 coins/pastry = 40 coins - Cost of tea: 4 participants * 100 grams/participant * (60 coins/1000 grams) = 24 coins - Total cost: 40 coins + 24 coins = 64 coins

Based on the calculations, it is more advantageous to buy everything for the tea party from the store owned by the Dodo, as the total cost is lower.

Answer: The Mad Hatter should buy everything for the tea party from the store owned by the Dodo.

2. How much money will the Mad Hatter save?

To calculate the amount of money the Mad Hatter will save, we need to compare the total cost from the store owned by the Caterpillar (with the discount) to the total cost from the store owned by the Dodo.

- Total cost from the store owned by the Caterpillar: 66.6 coins - Total cost from the store owned by the Dodo: 64 coins

The Mad Hatter will save: 66.6 coins - 64 coins = 2.6 coins.

Answer: The Mad Hatter will save 2.6 coins.

3. What is the total amount the Mad Hatter will spend?

The total amount the Mad Hatter will spend is the total cost from the store owned by the Dodo.

Answer: The Mad Hatter will spend 64 coins.
