Math problem (monkey eats peach)
There are five monkeys, a basket of peaches. Five monkeys plan to divide the peaches equally, but there is one more monkey. So all the monkeys go to bed, One monkey woke up first and wanted to share one more, so he ate one peach and divided the rest into five parts and took one of them. The second monkey didn't know what the previous monkey had to do when he woke up, so he did the same thing as the previous monkey, The third and fourth monkeys wake up and do the same thing. When the last monkey wakes up, he eats a peach. The remaining peach can be divided into five parts. How many peaches are there in the basket

3121
Let the first monkey take X1 peaches, the second one take X2,... And the fifth one take X5
Total y = 5x1 + 1 = 5x2 + 1 + (x1 + 1) - > 4x1 = 5x2 + 1 and so on
4x2=5x3+1
4x3=5x4+1
4x4=5x5+1
By iteration, 256x1 = 625x5 + 369 - > 256 (x1-x5) = 369 (x5 + 1)
Because both x1-x5 and X5 + 1 must be integers
So we get x1-x5 = 369
x5+1=256
Finally, we got
X5 = 255 X4 = 319 X3 = 399 x2 = 499 X1 = 624 total 3121

Monkey eat peach math problem. Who can?
A monkey picked a basket of peaches and ate one half of the remaining peaches every day. He didn't like it. If he ate one more, there would be only one peach left on the tenth day. How many peaches are there? Please explain and write a mathematical expression

Day 10: 1
Day 9: (1 + 1) x2 = 4
Day 8: (4 + 1) x2 = 10
Day 7: (10 + 1) x2 = 22
Day 6: (22 + 1) x2 = 46
The fifth day: (46 + 1) x2 = 94
Day 4: (94 + 1) x2 = 190
The third day: (190 + 1) x2 = 382
The next day: (382 + 1) x2 = 766
The first day: (766 + 1) x2 = 1534
A: there are 1534 peaches

A mathematical problem of "monkey eats peach"
In the morning, he gives three peaches to each monkey in group A and four peaches to each monkey in group B, giving a total of 705 peaches. In the evening, he gives four peaches to each monkey in group A and three peaches to each monkey in group B, giving a total of 716 peaches. There are () monkeys in group A?
If you want a formula, an easy to understand equation will do!

There are x a monkeys and Y B monkeys
3x+4y=705 （1)
4x+3y=716 (2)
Bottom up: X-Y = 11 (3)
(3) Multiply by 3: 3x-3y = 33 (4)
(2) (4) gives 7x = 749
x=107
Substituting (3) gives y = 96

When a and B buy the same kind of beverage, it costs 9 / 5 yuan per bottle. When a shop buys 10 bottles or more, it will be converted into 8. When B shop buys 5 bottles, it will get 1 free. Now it's time to buy 12 bottles. Which shop is the best place to buy

For the convenience of writing, I write 9 / 5 as a decimal, 9 / 5 = 1.8 to buy 12 bottles. It costs 12 × 1.8 × 0.8 = 17.28 (yuan) 12 △ 5 = 2 in a store 2. If you buy 10 bottles in store B, you will get two free. That is to say, if you buy 12 bottles, you only need to pay for 10 bottles. Store B needs 1.8 × 10 = 18 (yuan). Because 17.28 < 18, it's cost-effective to buy in store a

Xiao Ming bought exercise books. With this money, he bought 4 more than 1 yuan, and 6 less than 2 yuan. How much did Xiao Ming bring
Set X Yuan for each exercise book
4X+1=6X-2
-2X=-3
X=1.5
1.5 × 4 + 1 = 7 Step 2
-2X=-3
How to get
How does x on both sides get to one side,

Suppose that the first step 4x + 1 = 6x-2 4x + 1-4x = 6x-2-4x 1 = 2x-2 1 + 2 = 2x-2 + 2 3 = 2x 2x = 3 2x △ 2 = 3 △ 2 x = 1.5, and the second step 4 ×

When Xiao Ming buys exercise books, he pays the salesperson 4 copies more than 1 yuan and 6 copies less than 2 yuan. How much does Xiao Ming pay the salesperson and how much is each exercise book?
Use the equation!

Let each book be x yuan
According to the meaning of the title:
4x+1=6x-2
The solution is: x = 1.5
Answer: each exercise book is 1.5 yuan

When Xiaohua bought exercise books, the money he paid to the salesperson was more than 1 yuan for 4 copies, but less than 2 yuan for 6 copies. How much did Xiaohua pay to the salesperson? How much is each exercise book?

Unit price: (1 + 2) / (6-4), = 3 / 2, = 1.5 (yuan); Xiaohua pays the salesperson: 1.5 × 4 + 1 = 7 (yuan); answer: Xiaohua pays the salesperson 7 yuan, 1.5 yuan for each exercise book

Xiao Ming bought several exercise books at the retail price with 48 yuan. If he bought them at the wholesale price, they would be two yuan cheaper, just more

There are 3 × 16,4 × 12,6 × 8 factors with 48 greater than 2. According to the title, the two groups of factors can be expressed as X * y and (X-2) * (y + 4). Compared with the previous three groups, it is easy to know that they are 6 × 8 and 4 × 12, so the price is 6 yuan

Xiaoming bought several exercise books at the retail price with 48 yuan. If he bought them at the wholesale price, they would be 2 yuan cheaper, just 4 more?

Suppose the retail price is x yuan, then the wholesale price is X-2 yuan. According to the meaning of the question: 48x − 2 − 48x = 4, the solution is x = 6. After testing, x = 6 is the solution of the original equation. Answer: the retail price is 6 yuan per book
