Shopping malls hold sales promotion activities. A product is given a 10% discount first, and then a 20% discount. What percentage of the original price is the final price of the product?
1×90%×80%=72%
A: at the end of the day, the price of this product is 72% of the original price
In order to promote sales, a shopping mall increased the original price of a product by 50% and then sold it at 20% off the original price
Suppose that the original price of a is 10 yuan, and the increased price is 15 yuan, and 80% of 15 yuan is 12 yuan
Higher than the original price is inevitable
During the national day, many shopping malls carried out promotional activities one after another, and all the goods in shopping mall a were 20% off; shopping mall B offered 100 yuan for every 400 yuan bought, and 20 yuan in cash,
(1) If the customer's purchase amount is an integral multiple of 400 yuan, how much discount will mall B give the goods?
(2) Xiao Ming wants to buy a DVD with a price of 1000 yuan and a basketball with a price of 250 yuan. Which shopping mall should he go to? Why?
Give the idea of solving the problem to add points!
Suppose that the customer's purchase amount is 400N (n is a positive integer), then: the actual cost is (400n-100n-20n) yuan, so the discount rate of shopping mall B is: (400n-100n-20n) / 400N = 0.7, that is: the discount rate of shopping mall B is 70%; 2) the combination of DVD and basketball: shopping mall a: (1000 + 250)
The cost of a commodity is 80 yuan per piece, the selling price is 100 yuan, 100 pieces are sold every day
The cost of a commodity is 80 yuan per piece, and the selling price is 100 yuan. If the selling price is reduced by X% (10%, that is, 10%), the quantity of goods sold will be increased by 16%. If the daily turnover of the commodity is required to be at least 10260 yuan, and no loss, the value range of X is calculated
The original price is 100 yuan! The cost price is 80 yuan
100(1-0.1x)*100(1+0.16x)≥10260
(100-10x)(100+16x)≥10260
16x^2-60x+26≤0
(4x-13)(2x-1)≤0
1/2≤x≤13/4
Because I don't lose money
100(1-0.1x)≥80
x≤2
So 1 / 2 ≤ x ≤ 2
The cost price of a shopping mall is 80 yuan per unit. If you sell it at 100 yuan per unit, you can sell 1000 units. When the price of this commodity increases by 1 yuan per unit, the sales volume will decrease?
The cost price of a shopping mall is 80 yuan per unit. If you sell it at 100 yuan per unit, you can sell 1000 units. When the price of this commodity increases by 1 yuan per unit, the sales volume will decrease by 20 units. In order to earn the most profits, how much is the best price position?
It can be solved by equation
Set the price up by X Yuan
Profit y = (100 + x) * (1000-20x)
The first derivative of Y: 40x = 1000
X=25
So 25 yuan is the biggest profit
That is, the price is 125 yuan
If the cost price of a commodity is 100 yuan and the profit margin is between 40% and 60%, what is the price range of the commodity?

Suppose the selling price of this product is x, then: 40%
The cost price of a commodity is 100 yuan. If the price is increased by 50% and sold at a 20% discount, the price of the commodity is ()
A. 150 yuan B. 120 yuan C. 100 yuan D. 80 yuan
According to the meaning of the title, we get (1 + 50%) × 100 × 80% = 120 yuan
The cost of a commodity is 80 yuan per piece, and the selling price is 100 yuan. 100 pieces are sold every day. If the selling price is reduced by X% (10%), the number of goods sold will increase
1.6 the value range of X is 100 (1-0.1x) * 100 (1 + 0.16x) ≥ 10260 (why 0.16)
(100-10x)(100+16x)≥10260
16x^2-60x+26≤0
(4x-13)(2x-1)≤0
1/2≤x≤13/4
Because I don't lose money
100(1-0.1x)≥80
x≤2
So 1 / 2 ≤ x ≤ 2
16% is 0.16
If a commodity is sold at 80% of the price, it will still make 20% profit. What is the profit percentage of the price? Suppose the cost is one unit
It's a formula. Don't reprint it. It's due tomorrow,
Suppose the cost is unit = 1,
Percentage of profit = (selling price cost) / cost * 100%
Selling price = cost * (1 + percentage of profit)
Cost = selling price / (1 + percentage of profit)
Pricing = cost * (1 + percentage of profit at pricing)
Namely
Selling price = (1 + 20%) * 1 = 1.2
Pricing = 1.2/80% = 1.5
Pricing profit margin = (1.5-1) / 1 * 100% = 50%
Profit percentage at pricing = [(1 + 20%) / 80% - 1] / 1 * 100% = 50%
A commodity is priced at 20% profit, and then sold at a 10% discount to obtain a profit of 80 yuan. How much is the cost of this commodity?
And what I think
Let the cost of goods be X
X*（1+20%）*0.9-X=80
The solution is x = 1000
