2. The purchase price of a commodity is 200 yuan, and the selling price is 260 yuan
3. A store will increase the price of clothing by 40% and the price is 175 yuan. What is the cost price of each product?
4. The price of a jacket will be increased by 50% according to the cost price, and then it will be sold at a 20% discount due to the season. The price of each jacket will be 60 yuan. How much is the cost price of each jacket?
5. The store adjusts the price of a certain commodity and sells it at 25% of the original price. At this time, the profit margin of the commodity is 9%, and the purchase price of the commodity is 500 yuan?
6. A shop increases the price of a bicycle by 45% and then sells it at a 20% discount. As a result, each bicycle earns 50 yuan. What's the price of each bicycle?

1. The purchase price of a commodity is 15000 yuan, and the selling price is 18000 yuan
Profit = 18 000-15 000 = 3 000
Profit margin = (3000 / 15000) * 100% = 20%
2. The purchase price of a commodity is 200 yuan, and the selling price is 260 yuan
Profit = 260-200 = 60
Profit margin = (60 / 200) * 100% = 30%
3. A store will increase the price of clothing by 40% and the price is 175 yuan. What is the cost price of each product?
Cost price = 175 * (1 + 40%) = 125
4. The price of a jacket will be increased by 50% according to the cost price, and then it will be sold at a 20% discount due to the season. The price of each jacket will be 60 yuan. How much is the cost price of each jacket?
【60/（1-20%）】/（1+50%）=50
5. The store adjusts the price of a certain commodity and sells it at 25% of the original price. At this time, the profit margin of the commodity is 9%, and the purchase price of the commodity is 500 yuan?
【500*（1+9%）】/85%=641.18
6. A shop increases the price of a bicycle by 45% and then sells it at a 20% discount. As a result, each bicycle earns 50 yuan. What's the price of each bicycle?

The solution is x = 312.5

Profit and discount
1. In a store, 2400 yuan is used for football and basketball. Basketball is 15 more than football. Football is priced at 20 yuan. Basketball is priced at 24 yuan. The total profit is 820 yuan?
2. A certain commodity is sold at a fixed price and the profit is 45 yuan. Now the profit from selling 8 items at a discount of 85% is the same as that from selling 12 items at a discount of 35 yuan. How much is the price of each item?
Answer as much as you can

1. Set football x basketball x + 15
20x+24（x+15）-820=2400
X = 65 basketball 80
2. Set the price as X and the cost as x-45
0.85x*8-8*(x-45)=12(x-35)-12(x-45)
x=200

A mall implements discount sales. The purchase price of an electronic organ is 1800 yuan per unit. If it is sold at a 20% discount of the price, the profit will be less than 10% and the price will be lower
In what scope

Price x, according to the title (profit is less than 10% of the actual price) column inequality
x*80%-1800

The cost of a brand computer is 2400 yuan, and the price is 2980 yuan. If the store wants to sell at a discount with a profit of no less than 5%, it can sell at a discount
Sell at a discount of X

2400 * 0.05 = 120, that is, the profit should be at least 120 yuan
2980 * discount - 2400 ≥ 120
If I give an 8.50% discount, then according to the formula 2980 * 0.85-2400 = 133, I can give an 8.50% discount if it is greater than 120
