In order to solve the problem of people's difficulty in seeing a doctor, our government decided to reduce the price of drugs. After a 30% price increase in 1999, the price of a certain drug was reduced by 70% to a yuan in 2001. Then the price of this drug before the price increase in 1999 was 0___ Yuan

The price of a garment will be increased by 20% at first, and then decreased by 20%. Compared with the original price, is the price increased or decreased? What percentage is the increase or decrease?
Please, please.
Take the price of a garment as a unit
1 times (1 + 20%) = 120% (the current price is 120% of the original price) (regard this price as "a")
120% times (1-20%) = 96% (this price is 96% of the "a" price and 96% of the original price)
1 times (1-96%) = 4%
A: at this time, the price has been reduced by 4% compared with the original price

At present, a commodity is reduced by 10% for promotion. In order to keep the total amount of sales unchanged, the sales volume will increase compared with the original price______ The accuracy of the results was 0.1%
Suppose the unit price of sales is a, the sales volume is B, and the sales volume is m more than the original price, then the total amount of sales is ab. according to the meaning of the question: (1-10%) a · (1 + m) B = AB, the solution is: m ≈ 0.111 = 11.1%. So the answer is: 11.1%
First of all, we should reduce the price of a commodity by 10% to promote sales. In order to keep the sales amount unchanged, the sales volume should be increased by several yuan per time when it is sold at the original price
A bicycles from a to B, B bicycles from B to a, both of them are moving at an average speed. It is known that they set out at 8 am at the same time. By 10 am, they are 36 km apart, and by 12 noon, they are 36 km apart. The distance between a and B is calculated
The distance between a and B is x kilometers. It is known that both a and B are moving at an average speed, and they start at 8 am at the same time. By 10 am, they are 36 kilometers apart. It is said that a speed = B speed, a walk for two hours = B walk for two hours. From 10 am, they are 36 kilometers apart. By 12 noon, they are 36 kilometers apart
In order to keep the total amount of sales unchanged, how many percent of the sales volume should be increased compared with the original price,
If you want to use the equation of one variable, you have to explain how it comes at every step
Set the price as P and the sales volume as S
The sales amount is m = PS
Now the price is reduced by 20%, and the current price p '= (1-20%) P
The amount should remain unchanged. The current sales volume is set to s'
S'×P'=M
That is s' × (1-20%) P = M
And because M = PS, s' × (1-20%) = s,
So s' = s / 0.8 = 1.25s. The increased sales volume is 1.25s-s = 0.25s = 25% s
A: the sales volume is 25% higher than the original price
The wholesale price of a certain brand of color TV is 2000 yuan, and the retail price increases by 10%
