Summary. The questions that can't be searched by the homework help can be searched by text, that is, the questions are directly asked on the search interface, and there will be professional personnel in the background of the homework help to answer. When using the homework help, you also need to pay attention to these, otherwise there will be a situation where you can't find the questions:

1. When shooting the question, it must be aligned well, otherwise the question will not be accurately read, pay attention to the question should be placed in the middle when shooting. 2. Avoid taking multiple questions at the same time, because you can't answer multiple questions at the same time, so you can only shoot one question when you shoot questions. 3. You can only read the printed font if you take a photo and search the question, and if it is handwritten, it will definitely not be able to read it.

4. If the angle is incorrect and the stability is not enough, it will be blurry and the question will not be searched. 5. If the version has not been updated for too long, be sure to upgrade the software or uninstall the software and reinstall it, otherwise it will also affect the search questions.

30 is actually the current price, and a profit of 20% is 30 (1+20)=25 (yuan), and a loss of 20% is 30 (1-20)=yuan).

So at a loss. Hope it helps.

Make money x+20%x=30 x=x1-20%x1=30 x1=x+x1-(30+30)=

Sorry wrong Set the original price of the first and second clothes respectively is x and x1x+20%x=30 x=25x1-20%x1=30 x1=x+x1-(30+30)= loss of yuan, you can ask again.

Solution: Let the cost price be x, y, then.

x*(1+;y*(;

Two-way Polaris: x=25; y=

From 25+>60=30+30

Therefore, the mall lost yuan.

30 (1-20) = RMB).

30 (1+20) = 25 (yuan).

Yuan) 30-25 = 5 (yuan).

So the mall is losing money, losing yuan)

You should be.

30 (1-20) = RMB) (original price of the product).

30 (1+20) = 25 (yuan) (original price of the commodity) (yuan) (earning).

30-25 = 5 (yuan) (loss drop).

Yuan) A: Lost, lost 2 yuan.

Solution: The cost of two goods:

Yuan sold at a price of 30 30 60 yuan.

Two commodities are loss-making, loss-making: yuan.

In sixth grade, you started asking for help online,,, which isn't good. How not to discuss it with your classmates.

Earn 30 * 20 120 = 5 yuan.

Loss 30*20 (100-20) = yuan, so the loss is yuan.

Lost. The multiple of the cost price of the earned thing is 30 yuan, the cost price is 25, the loss is the multiple of the cost price is 30 yuan, and the cost price of this piece is, so it is a loss.

It's a loss, it's an experimental class. The question was already mentioned, but I forgot.

The area of the white triangle is equal to half the area of the rectangle.

Then the sum of the area of tulips and moon flowers also accounts for half of the area of the rectangle.

Tulips are known to account for 17 50, then the moon flowers account for 1 2 17 50 of the whole

Finally, multiply by the total area, and you get it.

And you're doing the right one.
