A commodity is priced at 20% of the profit, and then sold at a 15% discount, with a profit of 40 yuan

Pricing at 20% of profit
1、 It is priced at 20% of the cost and profit, with the formula of 40 (1.2 * 85% - 1) = 2000
2、 If the price is set at 20% of the sales profit, the equation (assuming the cost is x and the price is y) is as follows
Y-X=20%Y
Y*85%-X=40
By solving the above two equations, y = 800 and x = 640 are obtained

A commodity is priced at 30% profit and sold at 25% discount. The final profit is 84 yuan. How much is the cost of this commodity?

Suppose the cost price of the commodity is x yuan, then
（1+30%）*X*85%-X=84
0.105X=84
X=800
A: the cost of this product is 800 yuan
Or:
84÷｛（1+30%）×85%-1｝=800
A: the cost of this product is 800 yuan

How much do you need for a notebook and a pen? Male customer: I'll buy one
How much is the notebook and four pens?
Boss: just 18 yuan
Female customer: I bought a notebook and a pen for just 6 yuan

Let X be the notebook and y be the pen
x+y=6；
x+4y=18；
The solution is obtained;
x=2；y=4
If you only learn one yuan at a time, you can use this setting
Notebook is x, pen is 6-x;
We have X + 4 (6-x) = 18

The price of a famous brand laptop is 7500 yuan, 20% of the profit can be obtained by 20% discount

Let cost price be X
x*(1+20%)=7500*80%
X = 5000 yuan
Profit from selling at original price:
(7500-5000)/5000
=50%

Math problem: a computer store bought a batch of laptops and priced them at 30% profit. After selling 80% of these laptops, in order to sell them out as soon as possible,
In order to sell out as soon as possible, the franchised store sells the remaining laptops at half of the price. After selling out, what percentage of the total purchase price of these laptops does the franchised store actually make? (please explain in detail)

If the purchase price is 100%, i.e. 1, then the original price of 130% is 80%,
Later, half price 130% / 2 = 65% sold 20%,
Total sales 130% * 80% + 65% * 20% = 117%
So the profit is 17% of the purchase price

The price of a commodity is 408 yuan after 15% discount. How much is the original price of this commodity

Suppose the price of the goods is x yuan
0.85x=408
x=408÷0.85=480

The purchase price of a commodity is 300 yuan, the price is 400 yuan, and the profit margin is 20% when the commodity is sold at a discount?

Suppose the goods are sold at a discount of X. then 400 × X10 − 300 = 300 × 20%, the solution is: x = 9

If the purchase price of a commodity is 200 yuan and the original price is 300 yuan, and the profit margin after discount is 5%, the commodity is sold at the original price______ It's on sale at a discount

Suppose that the goods are sold at a discount of 70% of the original price. According to the equation, we get: (300x-200) △ 200 = 0.05, and the solution is: x = 0.7. Then the goods are sold at a discount of 70% of the original price
