Cake 5 yuan Coke 4 yuan small pay 50 yuan how many bottles of Coke and how many cakes can I buy?

There are only two answers to this question, because 50 yuan is specific, and if you want to spend it just now, you must first determine it with 4 yuan of Coke, and Coke only buys 5 or 10 bottles, if you buy 5 bottles of Coke, you can buy 6 cakes, and if you buy 10 bottles of Coke, you can buy 2 cakes.

You can buy up to 11 bottles of Coke and a cake, 11x4+5=49. You can buy at least 10 cakes, 1 bottle of Coke, 10x5+4=49.

There are 2 ways to buy.

5 surplus 5 can buy 5 + 1 = 6 cakes and 5 bottles of Coke.

You can buy 10 bottles of Coke and 2 cakes.

You can buy 6 cakes: 5x6 = 30 (yuan).

You can also buy 5 Cokes: 4 5 = 20 (yuan).

30 yuan + 20 yuan = 50 yuan.

When all 50 dollars are spent.

1) 6 pieces of cake, 5 bottles of Coke.

2) 2 pieces of cake and 10 bottles of Coke.

There is something wrong with the topic itself; Let's say you're asking about $50 that you have to spend.

Two unknowns, one equation, this is an indefinite equation with an infinite number of solutions.

50=5x+4y;

The deformation of the equation is:

5x=50-4y, the result is obtained by taking an integer.

x=10;y=0;

Cakes: 10 Coke: 0.

x=6;y=5;

Cakes: 6 Coke: 5 pieces.

x=2;y=10;

Cakes: 2 Coke: 10 pieces.

If only the cake has a maximum of: 50 5 = 10

If you buy Coke at most: 50 4 = 12

If it is a cake, Coke has the largest number of total is (4*5+5*6=50):

Six cakes, five bottles of Coke.

Summary. If you don't have any money left.

Then it is known that it cost 6 yuan to buy Coke, that is, a bottle of Coke costs 6 yuan, and 3 bottles can be 6 + 6 + 6 + = 18 yuan.

A: There is still 18 yuan left on three bottles of Coke.

Ask how much is the difference between four dollars for a cake, six dollars for a Coke, and three bottles of Coke.

Hello. It cost 6 yuan to buy Coke, and I asked how much it was to buy 3 bottles of Coke.

This question is a wrong one.

Because it is impossible to calculate how much money is left on the body.

If you don't have any money left.

Then it is known that it cost 6 yuan to buy Coke, that is, a bottle of Coke costs 6 yuan, and 3 bottles can be 6 + 6 + 6 + = 18 yuan.

A: There is still 18 yuan left on three bottles of Coke.

15+3 18 (yuan).

A: Xiaohong spent a total of 18 yuan.

Summary. 119 3 + 5 = 362 yuan, a total of 362 yuan.

Cake 119 yuan + Coca-Cola 5 yuan + buy three cakes and a bottle of Coca-Cola, a total of more money.

119 3 + 5 = 362 yuan, a total of 362 yuan.

A cake is 119 yuan, 3 cakes are 119 3 = 357 yuan, a bottle of Coke is 5 yuan, and the cake and Coke are 357 + 5 = 362 yuan.

A piece of cake is 4 yuan, and naughty has 15 yuan, which is enough to buy 3 cakes.

Equation according to the title:

3...Remainder 3

So enough to buy 3 pieces of cake.

Nature of division calculations:Formula: Dividend: Divide by this roll = quotient; Dividend quotient = divisor; Quotient divisor = dividend; Case with remainder:

Dividend Divisor = quotient ......Remainder (where the remainder is less than the divisor), divisor quotient + remainder = dividend.

Divide a number by the product of several numbers, and you can divide the remaining numbers by the various factors in the product in turn. The quotient of a number divided by two numbers is equal to the number divided by the dividend in the quotient and then multiplied by the divisor in the quotient. For example:

1. Because the 15 yuan of the large box has 20 yuan, and the 5 yuan of the small box is only 5 yuan, 1 yuan a piece, so it is cost-effective to buy a large box. 55 people need 55 pieces per person. Then you should buy two large boxes of 2*20 40 pieces, 3 boxes of small 3*5 15 pieces, and need 2*15+3*5 30+15 45 yuan.

This is the best solution.

2. The second is a large box of 20 pieces + 7 boxes of small 5*7 35 pieces, which requires a total of 15 + 35 50 yuan;

3. Again, it is 11 boxes of 5*11 55 pieces to buy all small boxes, which requires 55 yuan.

55 20 2 (box) ......15 (blocks).

15 5 3 (box).

15 2 30 (yuan).

3 5 15 (yuan).

30+15 45 (yuan).

A: A total of $45 is required.

A total of 55 pieces are required.

A large box is 20 pieces.

You need a large box of chocolates, but the chocolates don't open the box, so you need 2 large boxes of chocolates, which is a total of 40 pieces.

A total of 55 pieces are needed, and now the two large boxes are 40 pieces, which is still 15 pieces, and the small box is five pieces in a box, and 15 pieces is exactly 3 boxes.

Therefore, 55 yuan requires two large boxes and three small boxes, which is a total of 2*15+3*5=45 yuan.

There are a total of 55 people in the fourth grade, each person needs a total of 55 chocolates for a piece of chocolate, two boxes of 40 chocolates in a large box, 3 boxes of 15 chocolates in a small box, and two boxes of money for 15 2 30 yuan in a large box, and 5 5 25 yuan for 3 boxes of small boxes, a total of 55 yuan.

55 people, 1 yuan per person, 55 yuan, 20 2, two large boxes, there are 40 yuan, 15 2, 30 yuan, 55-40, 15 yuan, 3 small boxes, 5 3, 15 yuan, 30 + 15, a total of 45 yuan.

55 20 = 2 boxes mostly 15 (just 3 small sedan Zen boxes).

Answer: It costs 45 yuan for a total of sails.

55 20 2 (box) ......15 (blocks).

15 5 3 (box).

Therefore, you need to buy 2 boxes of large boxes and 3 boxes of small boxes, a total of need:

45 (Yuan Wumin).

A: A total of 45 yuan is required.

There are 55 people in the fourth grade, and the mountain bureau wants to buy 55 pieces of chocolate, you can buy two large boxes of teasing and relenting, and three boxes of ruined small boxes, you need.

2 15 + 5 3 = 45 yuan.

The large box of chocolate is 15 yuan and 20 yuan, and the small box is 5 yuan and 5 yuan, and the fourth grade is 55, if each person has a piece, how much does it cost?

Then you should buy 2 large boxes and 3 small boxes.

20x2 ten 5x3 55 blocks.

2x15 ten 5x3 30 ten 15 first trace 45 yuan.

Solution: 20 yuan to buy 2 boxes, 5 yuan to buy 3 boxes, 45 yuan; You can also buy 3 boxes for 45 yuan in a large box, and there are 5 pieces left.

It takes 15 nones to get one piece per person.

55 20 2 (box) ......15 people.

15 5 3 (box).

2x15+3x5=45 yuan.

A: A total of $45 is required.

45 yuan, first you can buy a big box of chocolates, buy a big box of chocolate pants to make a force, there are 2 20 in 55, there are 15 people left, you can buy another big box of chocolates, and he Chun can buy three more boxes of small boxes of chocolates, all of which are 15 yuan, so it adds up to a total of 45 yuan Zen Chong.
