Problem Analysis

The Mad Hatter is planning a tea party and needs to buy tea and pastries for himself and the other guests: the March Hare, Alice, the Cheshire Cat, and the Red Queen. There are two stores in Wonderland: one owned by the Caterpillar and the other by Dodo. The Caterpillar's store is far away and requires a delivery fee, but the Caterpillar is a good friend of the Mad Hatter and offers a discount on the total purchase amount (excluding delivery). The prices of tea and pastries differ between the two stores. 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 prices of tea and pastries at the Caterpillar's store and Dodo's store, taking into account the discount and delivery fee.

1. Which store should the Mad Hatter choose to buy everything for the tea party? - At the Caterpillar's store, the price of one pastry is 11 coins, and the price of one kilogram of tea is 50 coins. - At Dodo's store, the price of one pastry is 10 coins, and the price of one kilogram of tea is 60 coins. - Additionally, the Caterpillar offers a 10% discount on the total purchase amount (excluding delivery), but there is a delivery fee of 10 coins. - To determine which store is more cost-effective, we need to calculate the total cost at each store, taking into account the quantity of tea and pastries needed for the tea party. - The Mad Hatter needs to buy 100 grams of tea and one pastry for each participant, which means he needs to buy a total of 500 grams of tea and 5 pastries. - Let's calculate the total cost at each store:

- At the Caterpillar's store: - Cost of tea: 500 grams * 50 coins per kilogram = 25,000 coins. - Cost of pastries: 5 pastries * 11 coins per pastry = 55 coins. - Total cost (excluding delivery): 25,000 coins + 55 coins = 25,055 coins. - Discount: 10% of 25,055 coins = 2,505.5 coins. - Total cost (including discount): 25,055 coins - 2,505.5 coins = 22,549.5 coins.

- At Dodo's store: - Cost of tea: 500 grams * 60 coins per kilogram = 30,000 coins. - Cost of pastries: 5 pastries * 10 coins per pastry = 50 coins. - Total cost (excluding delivery): 30,000 coins + 50 coins = 30,050 coins.

- Comparing the total costs, it is more cost-effective for the Mad Hatter to buy everything for the tea party at the Caterpillar's store.

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 at the Caterpillar's store (including the discount) with the total cost at Dodo's store. - The total cost at the Caterpillar's store (including the discount) is 22,549.5 coins. - The total cost at Dodo's store is 30,050 coins. - The amount of money the Mad Hatter will save is the difference between these two costs: 30,050 coins - 22,549.5 coins = 7,500.5 coins.

3. What is the total amount the Mad Hatter will spend? - The total amount the Mad Hatter will spend is the total cost at the Caterpillar's store (including the discount) plus the delivery fee. - The total cost at the Caterpillar's store (including the discount) is 22,549.5 coins. - The delivery fee is 10 coins. - The total amount the Mad Hatter will spend is 22,549.5 coins + 10 coins = 22,559.5 coins.

Summary

To summarize: 1. The Mad Hatter should choose to buy everything for the tea party at the Caterpillar's store. 2. The Mad Hatter will save 7,500.5 coins by choosing the Caterpillar's store. 3. The Mad Hatter will spend a total of 22,559.5 coins for the tea party.
