I m sorry everyone.,I really won t.。。。

Last year's data is used as the base period.

1. The impact of this year's output on the total cost: last year's total cost = 6500 * 30 * 15 = 2925000

The impact of production = 6700 * 30 * 15 = 3015000-2925000 = 90000

2. The consumption of raw materials per unit of product, 6700 * 29 * 15 = 2914500-3015000 = -100500

3. The impact of the change in the unit price of raw materials on the total cost: 6700 * 29 * 14 = 2720200-2914500 = -194300

Combined with the above scores: 90000 + (-100500-194300) = -204800

The total cost of the product was reduced by 204,800 yuan compared with the previous year, mainly due to the increase in output, the reduction of the cost of unit consumption, and the reduction of the unit price of materials.

Is there still 10-1=9 9x3=27 27+2=29 30-29=1 on the question, where is the remaining 1 yuan? 、、Actually, the 10-1=9 is to fool you, because from 9x3=27 is the money that is spent, and the 1 yuan is now the money in the hands of 3 people, so it's actually very simple... 30-29+1=30

At the beginning, the 1 yuan was not an expense, and it shouldn't be subtracted from the expenses and the money still in hand, but it wasn't clear how to calculate In fact, the waiter and the boss were in a group, 3 people were in a group, so you can think about it, the boss actually charged a total of 27 yuan (25 yuan at the beginning, plus 2 yuan from the waiter), so that the 1 yuan in the hands of +3 people 27 + 3 = 30 is not just right? Oh, I hope you can understand the explanation... Hope it helps you o(o

Subtracting 2 is right, adding 3 is true, let's put it this way, the boss returns 30 yuan, and the little two deduct 27, then they actually spent 27 yuan, do you still want to use three people to spend 27 yuan plus 27 yuan for the small two, so adding 2 is incorrect, 2 is already in 27 yuan, 27 yuan plus 3 yuan returned is 30 yuan & 30 = 2 + 3 + 25

This problem is actually a mistake in the balance between "out" and "in", here "out" is that three people each spent 9 yuan, a total of 27 yuan, and "in" is the boss received 25 yuan and 2 yuan for Xiao Er's greed, 3 * 9 = 25 + 2.

Please take a look, are you going to give it to someone else after the big brother shows it to you tomorrow?

Garnet, a geological term, is one of the main rock-forming minerals in the upper mantle. Garnet crystals are very similar to the shape and color of pomegranate seeds, hence the name "garnet". Garnets with good color and high clarity can be gemstones.

Garnet, the English name for garnet, is derived from the Latin word "granatum", which means "like a seed". Garnet is commonly found in red, but its color is very diverse, covering almost the entire spectrum. In ancient China, it was known as Ziya Wu or Ziya Wu, a group of minerals that were used in the Bronze Age as gemstones and abrasives.

This is tourmaline. Natural color of each bead. The content of the light is different. This string is consistent with each other, so it is unlikely to be true.

Hello, stem base rot is harmful at the initial stage.

In the early flowering stage, the growth of plants accelerates, coupled with the changeable temperature, continuous rain, moist soil, and the wounds caused by agricultural operations lead to the invasion of pathogens and the infection of stem base rot.

Prevention and control methods: deal with the drainage work, increase the application of phosphorus and potassium fertilizer and biological fertilizer in the seedlings, remember to apply nitrogen fertilizer to enhance the stress resistance of the plant, spray the base of the stem with Bacillus subtilis plus seaweed sperm powder and chlorethoxaline, or spray the base of the stem with trichloroisocyanuric acid and fludioxonil, the control effect is very good.
