Each sapling is 16 yuan, buy three get one free, and now Xiaodong wants to buy 20, how much less tha

20 (3+1) is calculated according to the proposition

Problem solving ideas: The key words in the application problem are average, division is generally used, multiplication is generally used, and addition and subtraction are generally used for who is more or less than whom, and columnar formulas are applied according to the keywords. Problem solving process:

Answer: It actually costs 80 yuan less than the original.

Extended information "Vertical Calculation - Calculation Process": first align the last digit of the two multipliers, then use the second multiplier respectively, multiply a multiplier for each number from the last digit in turn, and finally add up the calculated result to be the product, if the multiplier is a decimal place, it can be expanded by the corresponding multiple, and finally the product is reduced by the corresponding multiple;

Problem solving: Step 1: 8 5=40

Step 2: 4 5 = 200

According to the above calculations, the sum is 240

If you have any doubts, please ask and be satisfied.

16 3 5 = 240 (yuan).

16 20 = 320 (yuan).

320-240 = 80 (yuan).

A: It actually costs 80 yuan less than the original.

16x20-3x5x16

80 (yuan) to buy 20 saplings costs 80 yuan less than the original.

It turned out to cost 16 20 = 320 yuan.

Buy three get one free is equal to a group of 16 3 = 48 yuan to buy 4.

20 buy 20 4=5 groups are fine.

48 5 = 240 yuan.

Now it costs 320-240=80 yuan less than the original.

It's 4 pieces cheaper each.

Analysis: The original price of each sapling is 16 yuan, now buy 3 and get one free, and buy 4 saplings with the original money of buying 3 saplings

16-12=4 (yuan).

16 times 3 divided by 4 equals 12 yuan.

16 minus 12 equals $4.

A: Each tree is 4 yuan cheaper.

16 3=48 (yuan) 48 4=12 (yuan) 16-12=4 (yuan) Answer: Each sapling is cheaper by 4 yuan.

16*3=48 yuan.

48 4 = 12 yuan.

16-12=4 (yuan).

So: 4 yuan cheaper per tree.

Let's start by calculating the price of three saplings.

16 times 3 equals 48

Calculate the average price of 4 saplings.

48 divided by 4 equals 12

Inexpensive**.

16 minus 12 equals 4

I buy up to 20 trees, including the one that I send. The calculation method is 20 yuan per sapling, and the total amount is 296 yuan, so it is to divide 296 by 20 is about equal to 15 trees, buy 3 trees and get one free, divide 15 trees by 3 trees bought is equal to 5 trees, and then add 15 trees to 5 trees equals 20 trees.

Summary. 24 4 = 6 3 6 = 1818 + 6 = 24 18 25 24 = yuan.

A sapling costs 25 yuan, buy three and get one free, buy 24, how much is actually each tree.

Kiss, the process of solving this problem is as follows: 25 (3+1)=25 4=25 4 yuan.

Can you all do it?

He also charged me 3 yuan and 8 dimes.

24 4 = 6 3 6 = 1818 + 6 = 24 18 25 24 = yuan.

The following is correct, you can take a look, you can ask if you don't understand.

I bought 18 and gave 6 away, and the price of 18 was 18 15, and I actually got 24 of them.

Divide the price of 18 trees by 24 trees to get the actual price of each tree.

How did those 18 trees come about?

I don't get it. There are 6 groups of 4 in 24, buy three get one free 3 6 = 18 This number is not understood.

I actually spent money to buy it, 18, and gave 6 away

To buy three trees, you need to pay 3*16=48 yuan, and giving one tree is equivalent to 48 yuan to buy four trees. 48 4 = 12 yuan per tree, which is 4 yuan cheaper.

16-16-3 (3-1) Teasing the stove.

16-48 4

16-124 (yuan).

Answer: Each Qingshu is cheap and 4 yuan.

Each sapling is 16 yuan, 2000 yuan can buy up to how many trees, 176 yuan can buy up to 14 trees, buy 3 such saplings get 1 free. 176÷16=11。You can buy 11 slippery 11 trees 11 3 = 3 more than 2, up to 3 trees, Hui let the remaining 2 trees are not enough to give 11 + 3 = 14 can be bought plus a total of 14 trees.

Summary. 3 25 = 75 yuan 275 75 = 3 ......50 yuan.

Each sapling is 25 yuan, in order to **, the merchant decided to buy 3 and get 1 free, how many saplings can be bought at most for 275 yuan?

Buy three get one free, indicating 75 yuan to buy 4 trees.

3 25 = 75 yuan 275 75 = 3 ......50 yuan.

3 4 = 12 trees, 50 25 = 2 trees, 12 + 2 = 14 trees.

You can buy up to 14 trees.

Hello, ask where did the 50 yuan after 275 divided by 75 equal to 3 come from.

That's the remainder.

Of the 275, there are 3 75s, and 1 50

It was originally 48 yuan for 3 trees, but now it is 48 yuan for 4 trees, and the answer is 4 yuan.
