This code takes a number as input and calculates the value of p based on the following conditions:

- If n is less than or equal to 20, p is calculated by multiplying n with 1.68 and rounding it to 2 decimal places.
- If n is greater than 20, p is calculated by multiplying the first 20 units with 1.68 and adding the remaining units multiplied by 1.98, then rounding it to 2 decimal places.

Finally, it prints the value of p.

Note: The code seems to be incomplete as there are no initializations for variables 'n' and 'p'.
