fixed and variable cost
Fixed and variable frame rate
In terms of frame rate, a constant frame rate (CHF) refers to a constant frame rate during video playback or image display. For example, movies were usually played at a constant frame rate of 24 frames per second, which meant that 24 frames of images were displayed steadily every second during the playback process, thus providing a stable and smooth visual experience. Its advantage was that the rhythm of the images was stable, which made it easy to produce and display standard video content. For example, film production, traditional animation production, and so on mostly used a constant frame rate.
The variable frame rate (VFF) was a frame rate that was not fixed during video playback or image display. It could be changed according to the video content or display requirements. For example, in some video compression algorithms, when the image content changes slightly, the frame rate may be reduced to reduce the amount of data; when the image content changes drastically, such as when the scene changes rapidly, the frame rate may be increased to ensure the smoothness and visual effect of the image. The variable frame rate was widely used in modern video coding technology. It could compress video data more effectively while ensuring visual quality. It was especially suitable for some video application scenarios that required the frame rate to be adjusted according to the scene, such as network video streaming. The frame rate was adjusted according to the network width and the image content.

A certain publishing house published a book called auxiliary books. The fixed cost was 50000 yuan, and the variable cost of each book was 0.50 yuan. If each book was priced at 3…
The fixed cost of each supplementary book is 50000 yuan, and the variable cost is 0.50 yuan. The profit for each book sold is:
Profits = Fixed costs x Sales volume-variable costs
According to the data given in the question, the price of each book was 3 yuan:
Fixed cost x sales volume = 50000 yuan x 3 books-0.50 yuan x 1 book = 150000 yuan-0.50 yuan = 14995050 yuan
Therefore, the profit for every book sold was:
Profits = 150000 yuan x 1 book- 050 yuan x 1 book = 150000 yuan- 050 yuan = 14995050 yuan
The answer was that the profit for every book sold was 14995050 yuan.

Save the php variable as txt
To save a variable as a txtfile in Python, the following are some common methods:
1. If it was a simple text string variable:
- You can use the `file_put_contents` function. For example, if you want to save the string variable `$data` to a file named `output.txt', you can write`file_put_contents('output.txt',$data);`.
- You can also use the `fopen`,`fwrite`, and `fclose` functions. It was as follows:
- First, open the file: `$fft = fopen('output.txt',' w') or die("can't create file output.txt'");`, where `'w'` means to open the file in write mode. If the file doesn't exist, it will be created, and if it exists, it will be overwritten.
- Then write the data: Assuming the variable is `$data`, then `fwrite($fft, $data);`.
- Finally, close the file: `fclose($fft);`.
2. If it is an array variable:
- You can serialize the array first and then save it to a file. For example, you can serialize the array using the `serialize` function and save it to a file using `file_put_contents`. Assuming the array is `$array`, the code is as follows:
- `$serializedArray = serialize($array);`
- `file_put_contents('output.txt', $serializedArray);`。
- If you want to read and restore the array, you can use the `unserialize` function, for example,`$restoredArray = unserialize(file_get_contents('output.txt'));`.
