The original price of a commodity is 400 yuan. First, the price is increased by 20%. Later, the price is reduced by 20%. What's the current price
(400 + 20% × 400) × (1-20%) = 384 yuan
The original price of a commodity was 100 yuan. First it was reduced by 10%, then it was increased by 10%. How much is the current price
99 yuan. It's interesting. I want to ask this
If the purchase price of a commodity is 1500 yuan, the price will be marked after 40% increase. If it is sold at a discount and the profit margin is 20%, how much discount is the commodity sold?
Equation of first degree with one variable
Price = 1500 * (1 + 40%) = 2100
We can get a discount of X
Profit rate = profit / cost × 100% = (2100 * x-1500) / 1500 × 100% = 20%
X=0.86
The purchase price of a certain commodity is 180 yuan. When it is sold at a 10% discount on the marked price, the profit margin is 20%______ Yuan
Suppose the price of this commodity is x yuan, 90% x-180 = 180 × 20% x = 240, the price of this commodity is 240 yuan
If a store sells a commodity at a 10% discount on its price, it can still get a 20% profit margin. If the purchase price of the commodity is 30 yuan per piece, then the price is 30 yuan per piece______ Yuan
Suppose the price is x yuan. According to the equation: 90% X-30 = 30 × 20%, the solution is x = 40, then the price is 40 yuan per piece
A batch of color TV sets, originally priced at 4800 yuan, will be sold at the original 10% discount after a period of time. At this time, the profit margin is 9%. How much is the purchase price?
Purchase price = 4800 × 90% △ 1 + 9% = 4320 △ 1.09 ≈ 3963.3 yuan
The price of each color TV set is increased by 40% according to the purchase price, and then it is sold at a 20% discount. Each color TV makes 300 yuan. How much is the purchase price of the color TV set? What is the profit margin?
The purchase price is 2500 yuan
Profit margin 0.12
The purchase price of a color TV set in a shopping mall is 2100 yuan. When it is sold at a 10% discount on the price, the profit margin is 20%?
It's the equation!
Thank you for your help! I'll treat you to beef noodles and two poached eggs in the future!
Suppose the price of this color TV set is x yuan, according to the meaning of the title
90％x=2100*(1+20％)
90％x=2520
x=2800
The price of this color TV is 2800 yuan
If the purchase price of a commodity is 250 yuan and the profit margin is 15.2% when it is sold at a 10% discount on the marked price, then the marked price of each commodity is 100 yuan______ ．
Suppose the price of each item is x yuan, X × 90% = 250 × (1 + 15.2%), and the solution is x = 320
