Gọi số gói mà ông vịt Scrooge mua của McVees và Jays là \(x,y.\) Điều kiện: \(x,y\)  là số tự nhiên. Nếu số người ở hội nghị là \(N\) thì ta có phương trình \(6x+5y=N.\)

a) Nếu ông vịt phải mua cho 58 người, ông chỉ cần mua của McVees 3 gói và của Jays là 8 gói. Khi đó \(6x+5y=6\times3+5\times8=58.\) 

b)  Bài toán yêu cầu chúng ta xác định số nguyên \(N\) lớn nhất mà ông vịt keo kiệt bắt buộc phải mua thừa ra một số gói Bim bim, nếu muốn đảm bảo mỗi người trong hội nghị phải được ăn đúng 1 gói Bim bim.   

Đầu tiên ta nhận xét rằng nếu số người \(N\) chia hết cho 5 thì ông Vịt của chúng ta không cần phải phí phạm tiền của mình, vì khi đó ông ấy chỉ việc mua của bạn Jays \(\frac{N}{5}\) gói, còn không mua của McVees. 

Khi  \(N=20\) ông Vịt cần mua \(\frac{N}{5}=4\) gói của Jays, không mua của McVees. Nếu \(N=21\)  ông chỉ cần giảm số gói mua của Jays đi 1 và tăng số gói của mua của McVees lên 1, tức là mua của McVees 1 gói và của Jays 4 gói. Khi đó số bim bim mua là \(6\times1+5\times3=21=N.\) Tương tự cho \(N=22,23,24.\) VÌ khi \(N\ge20,N\vdots5\) thì số gói mua của Jays là \(\frac{N}{5}\ge4\to\) bằng cách trên, khi \(N\) tăng thêm 1 thì số gói mua của Jays giảm đi 1 và số gói mua của McVees tăng thêm 1. \(N\) sẽ tăng cho đến khi \(N+5\) ta lại gặp một số chia hết cho 5 và có thể lặp lại điều trên. 

Cuối cùng khi \(N=19\) thì phương trình \(6x+5y=19\) không có nghiệm tự nhiên, thực vậy \(6x\le19\to x\le3\to x=0,1,2,3\). Tuy nhiên \(19\) chia cho \(5\) dư \(4\) nên cả \(4\) trường hợp này đều không thoả mãn. (hoặc thử trực tiếp).

Vậy số \(N\) lớn nhất là \(19.\) Khi \(N>19\) thì ông Vịt sẽ tiết kiệm được tiền của mình khi mà không cần phải mua thừa ra số gói Bim-bim.

Chocolate

We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it’s an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers.

Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say “Ugh!” and run away. Workers must first dry and then roast the beans. This removes the bitter taste.

The word “chocolate” comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink.

When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion.

In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better.

Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and, of course, an ice cream sundae with hot fudge sauce.

Sô cô la

Bây giờ chúng ta nghĩ đến chocolate là ngọt, nhưng một khi nó đã cay đắng. Chúng tôi nghĩ về nó như một kẹo, nhưng một khi nó là một loại thuốc. Ngày nay, sô cô la có thể là đồ uống nóng, một món tráng miệng đông lạnh, hoặc chỉ là một bữa ăn nhẹ. Đôi khi nó là một thành phần trong bữa ăn chính. Người Mê-hi-cô nấu sốt nóng sốt sô-cô-la và gọi nó là gà. Người Mexicans cũng ăn sôcôla với gia vị như ớt.

Sôcôla là sản phẩm của cây ca cao nhiệt đới. Các hạt cà phê hương vị rất cay đắng rằng ngay cả những con khỉ nói "Ugh" và chạy đi. Người lao động phải khô trước và sau đó rang hạt cà phê. Điều này sẽ loại bỏ được vị đắng.

Từ "sô cô la" có nguồn gốc từ tiếng Maya. Người Maya là những người cổ xưa từng sống ở Mexico. Họ đánh giá cây ca cao. Một số sử dụng đậu để lấy tiền, trong khi những người khác nghiền nát họ để uống.

Khi người Tây Ban Nha đến Mexico vào thế kỷ thứ mười sáu, họ cũng bắt đầu uống cacao. Bởi vì thức uống rất mạnh và cay đắng, họ nghĩ đó là một loại thuốc. Không ai có ý tưởng thêm đường. Người Tây Ban Nha lấy một ít đậu trở lại châu Âu và mở quán cà phê. Những người giàu có đã uống cacao và nói nó rất tốt cho việc tiêu hóa.

Vào những năm 1800, chủ một nhà máy sôcôla ở Anh đã phát hiện ra rằng đường đã loại bỏ được vị đắng của cacao. Nó nhanh chóng trở thành loại đồ uống rẻ tiền và phổ biến. Ngay sau đó, một nhà máy đã tạo ra khối rắn chắc đầu tiên của sôcôla ngọt. Sau đó, một nhà máy trộn sữa và sô cô la với nhau. Người ta thích hương vị của sôcôla sữa tốt hơn.

Bên cạnh thanh kẹo sôcôla, một trong những món ăn nhẹ phổ biến nhất của người Mỹ là bánh cookie sô cô la. Các món tráng miệng yêu thích là bánh kem sô cô la và, tất nhiên, kem kem với sốt nóng hổi
