7,200 yuan in the first year, an annual increase of 12 percent, how much is it after 15 years?

a1=7200, a2=, .a15=

The money paid each year is proportional to the series, and the proportional series is summed.

sn=a1(

60000 ( Rounded to the nearest cent.)

268, RMB.

Hope, thank you.

The first year is 7200, the second year is 7200 (1+12%), the third year is 7200 (1+12%), and the fifteenth year is 7200 (1+12%) = 7200 yuan.

According to the length of service, 100 yuan for each year of work. And so on, the pension for 10 years of service is 1,000 yuan. The pension for 20 years of service is 2,000 yuan, the pension for 30 years of service is 3,000 yuan, and the pension for 40 years of service is 4,000 yuan.

There is no distinction between senior workers, intermediate workers, or ordinary workers. Pensions are equal. Civil servants should also be equal, regardless of their position.

The same as the worker's pension. The implementation will be completed within three years.

Let's give you a formula: 7200 multiplied by (1+12%) to the power of 15 = 39410

For a series, if the value of each term from the second term of the series is not less than the value of the term before it, then such a series is said to be an increasing series.

Summary. Hello, the calculation is simply multiplied by each year.

10% is actually that, then add the original 1 is.

For example, if it is 7,000 this year, it will be 7,000 next year, and 7,700 the year after next.

This question examines the calculation of exponents.

7000 increases by ten percent every year.

Hello, I am Mr. Fang Tengfei! I have seen your question, since the answer text takes time, so please be patient for 3 minutes Thank you

Hello, the calculation method is to multiply each year by the fact that is, then add the original 1 is. For example, if it is 7,000 this year, it will be 7,000 next year, and 7,700 the year after next. This question examines the calculation of exponents.

Solution: 1000* yuan in the first year.

Second year: 1030* RMB.

Year 3: Yuan.

Year 4: Yuan.

Fifth year: Yuan.

And so on, the fifteenth year is about 1,512 yuan.

Summary. Hello, it is a pleasure to help you with your studies. I've seen your problem, so I'm going to do the math for you right now, and I hope you will be patient for a while

12,000 yuan per year in 10% increments**, how much is the total after 20 years.

Hello, it is a pleasure to help you with your studies. I have seen your topic, and now Chi Chun is going to calculate the grinding for you right away, I hope you will wait patiently for a while

Hello, after detailed calculations, 12,000 yuan per year in 10% increments**, 20 years later, a total of 80,730 yuan.

This topic is based on the double-entry calculation of the growth rate of the town of Chong, which is growing by 10% per year. Then, if the scattered ruin rises on the basis of 12,000 yuan, you will get about 80,730 yuan after 20 years.

You can make further inquiries after seeing the calculation method. Because this can only be done with the help of a calculator. In short, I hope to be able to help you with the roundness of the waiter, and I wish you <> progress in your studies

The teacher asks you to write down the calculation steps.

Please wait a moment, now for the other students, later.

Consider 12,000 times (1+10%) to the 20th power.

In the end, it was 80,730 yuan.

Yes. The teacher will ask you how much it will be in 50 years.

The calculations can be done for you, but the teacher would like you to support <>

Good. Then you can also consider starting a new round of consultation.

The teacher's 12,000 yuan per year is increased by 10 percent, and the total amount is after 50 years.

In order to. I can do the calculations for you.

You need to support me too. This calculation is not a simple one.

It seems that you value money more than knowledge.

20 years of 10% annual growth, can be seen as 20 power, 17000 (.

The annual growth rate is 10%, the first year is 17000 (1+10%), the second year is 17000 (1+10%), so the 20th year is 17000 (1+10%) 17000 yuan.

It increased by 20% every 5 years, and after 20 years it doubled to 140,000*.

Summary. This question examines the question of the growth rate, the growth rate (1+2%) 17, then 27 years later, it will be, 9000 (1+2%) 17.

9,000 yuan increases by two percent every year, and how much after 17 years.

Kiss Huai shirt has found the relevant knowledge lead front cavity point is writing a detailed process for you This question examines the growth rate of the problem, the growth rate (1+2%) 17, then 27 years later, 9000 (1+2%) 17.

When calculating, a crack must be taken seriously, and the bridge is fine

Summary. Dear, I'm happy to answer for you<> 1,500 yuan increases by 10% every three years, to a total of 2,400 yuan in 20 years. 1500 times 10% = 150, 20 divided by 3 =, 150 times 6 + 1500 = 2400

Kiss, Expand: Primary school math application problems are usually divided into two categories: simple application problems that are solved only by addition, subtraction, multiplication, and division operations; A compound problem that needs to be solved in two or more steps.

In the past, Chinese application problems usually required the description to meet three requirements: no contradiction, that is, there should be no contradiction between conditions, conditions and problems; Completeness, i.e., the conditions must be sufficient to ensure that the value of the unknown quantity is obtained from the condition; Independence, i.e. several known conditions cannot be pushed into each other. <>

Answer? I want answers.

Dear, the answer has been sent to you. 2400 yuan.

Kiss. Including the formula process, it has also been sent to you.

Look at the answer I want.

1,500 yuan is increased by 10% every three years, and how much is it for 20 years.

Yours, twenty years, 2400, what is it?

Dear, the answer is yes.

That's how much it is.

Kiss, if you keep two decimal places, oh.

Dear, 4,157 yuan triangle quarter and one centimeter five hao.
