The profit of a chemical plant in January 2009 was 2 million yuan

1) According to the image, the inverse proportional function image passes through (1,200), let the inverse proportional function be y=$ frac$, then $ frac$=200, the solution is k=200, the inverse proportional function is y=$ frac$(x 5), when x=5, y=40, let the analytic formula of the function after the completion of the renovation project be y=20x+b, then 20 5+b=40, the solution is b=-60, and the analytical formula of the function after the completion of the renovation project is y=20x-60;

2) When y=200, 20x-60=200, the solution x=13 After 8 months, the profit of the factory can reach 2 million yuan;

3) When y=100, $ frac$=100, the solution is x=2, 20x-60=100, the solution is x=8, and the capital tension period is 8-2-1=5 months

y=200/x(x<=5),y=40+20*(x-5)(x>=6)

x=13,13-5=8.After the completion of the pollution control renovation project, the plant's monthly profit was only able to reach the level of January 2009.

100,x<8,200/x<100,x>2,x=3,4,5,6,7.The plant's financial constraints lasted for a total of 5 months.

1. If the profit in 2008 is 12 million yuan, the profit in 2010 is: 2010 profit = 12 million 20% = 2.4 million, 240 20 = 12 Therefore, every 1% increase is 120,000.

2. The calculation method of profit in the reporting period is as follows: profit in the reporting period = profit in the base period Profit growth rate in the reporting period (profit in the base period = 12 million, and the profit growth rate in the reporting period is 20%).

Extended Resources: Introduction to Income Statement.

1. Structure. The income statement generally has two parts: the first and the main statement. The first part of the table indicates the name of the report, the preparation unit, the preparation date, the report number, the currency name, the unit of measurement, etc.; The positive statement is the main body of the income statement, reflecting the various items and calculation processes that form the operating results, so this statement was once called the profit and loss calculation book.

2. Format. There are two types of income statement formats: single-step income statement and multi-step income statement. A single-step income statement is to list all the income for the current period together and then list all the expenses together, and subtract the two to get the net profit or loss for the current period.

The multi-step income statement is to classify the income, expenses and expenditure items of the current period according to their nature, and list some intermediate profit indicators according to the main links of profit formation, such as operating profit, total profit and net profit, and calculate the net profit and loss of the current period step by step.

3. Multi-step.

In China, the income statement adopts a multi-step type, and each item is usually divided into two columns: "number of this month" and "cumulative number of this year". The "Number of Months" column reflects the actual number of items in this month; When preparing the interim financial and accounting report, fill in the cumulative actual number of the same period of the previous year; When compiling the annual financial and accounting report, fill in the cumulative actual number of occurrences for the whole year of the previous year. If the names and contents of the items in the income statement of the previous year are inconsistent with those of the current year, the names and figures of the items in the income statement of the previous year shall be adjusted according to the caliber of the year in which they are reported, and shall be filled in the column of "number of the previous year" in this statement.

Profit in the reporting period = profit in the base period Profit growth rate in the reporting period.

Profit in the base period = 12 million, and the profit growth rate in the reporting period is 20%): 2010 profit = 12 million 20%.

2.4 million. 240 20=12 So, every 1% increase is 120,000.

A chemical plant in January 2012 profit of 2 million yuan, set January 2012 as the first month, the profit of the x month of y million yuan, due to the pollution exceedance, the plant decided to limit production from the end of January 2012, and invested funds to control pollution, resulting in a significant decline in monthly profits, from January to May, y and x are inversely proportional. By the end of May, the pollution control project was successfully completed, and from then on, the plant's monthly profit increased by 200,000 yuan compared with the previous month.

1) The corresponding functional relationship between y and x during the pollution control period of the chemical plant and after the completion of the pollution control transformation project is obtained.

2) After the completion of the pollution control renovation project, how many months will the monthly profit of the plant reach the level of January 2012?

3) When the monthly profit is less than 1 million yuan, it is the factory's tight capital period, and the factory's capital shortage period is how many months?

If 200 people produce, 200 2100 4 = 105000 bags can be produced in a year.

The raw materials in 2009 can be used for the production of liquid Yukai (1200+800-200) 1000 20=90000 bags 105000 bags.

Because 80,000 bags, 90,000 bags, 105,000 bags.

Therefore, in 2009, the maximum production volume of this product was 90,000 bags.

Have fun.

Hello, I am your life consultant Xiaonan Mohe teacher, I am very happy to answer for you, it will take about three minutes to solve the blind staring and digging answer, please wait patiently

Hello dear, please wait a minute

It's counting. Hello, the basic P/E ratio is 1%, and the P/E ratio is 1% hope it helps you.

Hello, a certain line of profit in May 2010 was 12 billion yuan, a year-on-year increase.

Fold. According to the growth rate.

Reporting period - base period) The calculation formula of the number of base periods * 100%.

Growth rate in May 2010 = (profit in May '10 - profit in May '09) Profit in May '09 * 100%.

120-09 May profit) 09 May Li with Kairun = from it, can be found 09 May profit = 4.5 billion yuan.

Suppose: The total output value of the previous year is x the total expenditure is y

Then: x-y=100

1+20%)x-(1-10%)y=240 solution: x=500 y=260

Therefore, the total output value of the previous year was 5 million yuan, and the total expenditure was 2.6 million yuan.
